Norway

By Jack Nuclkes: UW-Madison Undergraduate who is on an IRES Neutrino Astrophysics Internship in Sweden in Summer 2016.

Four days after returning from Switzerland, we again packed our backpacks and began our trip to Norway.  After our long haul to the Alps, we were all glad that we only had a mere 30 hours on trains planned for the weekend.

By Friday morning, we reached Bergen, a city on the west coast of Norway.  We then headed back east to Voss (the town that is the namesake for the “artesian” water brand) to meet a bus that took us down an 18%-grade road to Gudvangen, where we boarded a boat for an unbelievably beautiful cruise through the Nærøyfjord.  We had read that this deep, narrow fjord offers some of the best scenery anywhere in the world, and it certainly delivered.  Two hours later, the boat deposited us in Flåm. The world-famous Flamsbana train then took us by waterfalls and through hand-dug tunnels from sea level to Myrdal at 3,000 feet. One more train brought us back to Bergen. We spent the evening strolling through the fish market and exploring a fortress before getting on the night train to Oslo.

We arrived in the Norwegian capital before the city really woke up, so for two hours we had the streets to ourselves.  Throughout the day, we saw the obligatory sights, including the modern opera house, a tour of the city hall (where we learned so much we were half expecting to get a diploma before we left), and a walk through a large sculpture park.  By the afternoon, we were all out of granola and PB&J supplies, so Nick K. grabbed what he said was a delicious barbecue-flavored hot dog, suspiciously on sale, from one of the many 7-Elevens in the city.  Shortly after, we caught the train back to Stockholm, concluding another great weekend trip.

 

Switzerland

By Jack Nuclkes: UW-Madison Undergraduate who is on an IRES Neutrino Astrophysics Internship in Sweden in Summer 2016.

We left Stockholm at 7:00 a.m. on a Friday morning, each toting a backpack stuffed with, among other necessities, water, bread, peanut butter, canned tuna, and fresh socks. During the next 24 hours, four trains carried us to Switzerland. We sped through the Swedish countryside to Malmö where we hopped on a commuter train to Copenhagen. To reach the European mainland, the next train rolled onto a ferry and we cruised across the Baltic before continuing on to Hamburg, where our steady southward progress was interrupted by an agonizing three hour wait for the night train to Basel. At precisely the minute it was scheduled to leave, a faded, rusty, tin can of a train screeched to a halt at the platform where we were waiting.

We spent the next ten hours in a blurry purgatory, half-sleeping at best between the screams of toddlers and the strange lights that flashed through the window of our compartment. However, the next morning, as we ate our breakfast on a bench in an empty Basel train station, we unanimously agreed that the journey was worth it. We were in Switzerland.

Two more quick trains took us to Lauterbrunnen, a small farm village in an alpine valley that felt quintessentially Swiss. Surrounded by cliffs, waterfalls, and with views of snowy peaks, we wandered around and enjoyed the scenery. Church bells filled the air intermittently as cows grazed in the fields and wispy clouds floated along the clifftops. In the afternoon, we headed north to Bern, the Swiss federal city. We strolled through the flag-lined streets, snapped photos of the turquoise Aare River, and admired the statues and architecture. As the sun began to set, we returned to the train station to begin our journey back to Scandinavia.

To get home we repeated our trip from Stockholm to Basel in reverse. Feeling the effects of having not showered three days, we sat tiredly and watched the scenery out the window of the trains slowly change from the farm fields of Germany to the windmills of Denmark and finally to the rocky soil and pine trees of Sweden. At close to midnight on Sunday, we reached our apartment, feeling grateful to be home but even more-so, glad to have been to three new countries and the Swiss Alps.

Busy Summer 2016 at UWRF

One month has gone by and this is our first post for summer 2016. We have been very busy getting; first with and intense first week settling into River Falls, getting paperwork done, learning python programming, particle physics, neutrino astrophysics and exploring many aspects of IceCube. This summer we have six REU students from all over the US. They are Megan Davis (MSU), Kristine Skul (Chicago City Colleges), Lorena Mezini (Stony Brook U), Roman Gradford (Normanale College, MN), Mykalin Jones (WPI), and Chris Patenaude(Clatsop College, Oregon). They are joined by five UWRF students; Alex Haas, Marium Asif, Dylan Frikken, Joseph Wagner, and Mitch Ahlswede. All student are working on projects either on the IceCube Netutrino Observatory or on the Neutron Monitors at UWRF and the South Pole. Fhon is also visiting from Thailand for the summer.

Megan Davis arrived first, a few days early so she could get an early start on her project. She and Chris are working with Dr. McCann. They are looking at the properties of optical fibres that can be used as light sensors for the next generation of IceCube, IceCube-Gen2.

Everyone else

arrived in the a few days later.  As usual, the first thing we do is a week of prep for the IceCube bootcamp. After the first week of bootcamp prep we headed off on the usual trip across the state to Madison. The road trip is always a time when we get to know each other a bit better and  a chance for REUs to see a little more of Wisconsin.

The bootcamp was organized a bit different this year. It started on Saturday with a two day pre-bootcamp, followed by two days of beginner and three days of advanced bootcamp. We stayed for the first four days. This belated first post ends here but stay tuned for more frequent posts in the next few weeks. Meanwhile, here are some photos from the first weeks.

Stockholm Summer Starts

Editor’s Note: Five undergrads are taking part in an NSF Funded IRES program in Sweden this year. Here they start to chronicle their adventures. They are Vanessa Esaw (University of Minnesota and 2015 UWRF REU, Nick Kulacz and Nick Jensen (UWRF), Jack Nuckles (UW-Madison), and Samantha Pedek (UWRF)

After three flights over the course of a full day, we all made it safely to Stockholm, Sweden on Sunday May 22, 2016. For many of us, this was the first time out of the country. The flights, though long, were uneventful. Vanessa and Sam are staying in an adorable apartment in northern Stockholm for the first week before moving to southern Stockholm for the rest of the time.

Nick, Nick and Jack are staying in a tiny apartment in northern Stockholm. The doors have been the biggest adversary as they open the wrong way almost all the time, and the shower is not enclosed and therefore gets the bathroom floor all wet. One of our first tasks when we arrived was finding a grocery store. It is unbelievably difficult to shop in a market for things in a different language and are not where you “expect” them to be!

The people here are very hospitable and friendly and almost everyone speaks English. Overall, Swedes seems happy and content. The fact that summer holiday is right around the corner may have something to do with that. Summer holiday is from the end of June until the beginning of August. Basically the entire country vacations during that time!

The weather here is very similar to weather in Wisconsin when we left, which is welcoming. One major difference though is how long the sun is up. The sun starts to rise at around 4:00am and doesn’t set until about 10:00pm. The majority of our first week consisted of settling in and adjusting to the new environment.

Midway through the week we all settled on projects for the summer. As a brief overview: Nick and Nick are working on building a one meter cubed to scale LED model of IceCube, Jack is modeling cosmic ray sources in the galactic plane, Vanessa is using machine learning algorithms to optimize muon track reconstruction and Sam is simulating a version of Gen 2 to check the likelihood of detecting extragalactic supernova.

The work environment here is very relaxed. Both the professors and the grad students are very helpful and flexible. Once a week we have fika, which is a staple of Swedish culture. Everyone from the office gets together for a coffee break with a light snack. It is a chance to socialize and catch up with everyone in the office.

This Friday, Kip Thorne visited the University of Stockholm to give a talk on gravitational waves, which were recently discovered by LIGO. Kip Thorne was one of the original founders of LIGO. The talk was very comprehensive and we all enjoyed it.

Robert Leaves the Pole, Finally!

By Robert Zill (Undergraduate DuPage and NIU)

Back in McMurdo, we finished up the final tasks we had with the troubled tube of the neutron monitor and then we got one more exploration opportunity. We were able to visit Discovery Hut which is a structure just a short walk from “downtown” McMurdo that was built in 1902 as a rest stop of sorts for early Antarctic explorers. They take the preservation of original artifacts very seriously and so you are not allowed to touch anything. No, not even the rotting seals that have been in there for decades! Once you got over the smell though, it was very interesting to have a look around. There were old crates that had Scott’s name on them. He was one of the early explorers in Antarctica and leader of the second group to reach the South Pole. There were pans on the kitchen stove with bits of seal meat still in them and there were places where they had started to rip the ceiling down to use for firewood. It was a veryintriguing and very well preserved site to see.

Well, here we are, waiting a few more hours for our flight to take us back to New Zealand. It has been an intense experience down here, but I am also happy to be leaving as well. Spending a month in New Zealand is scary and exciting at the same time, but I look forward to seeing what the country has to offer me. I’ve met many people down here who are also spending time in NZ and a few of us many hopefully cross paths at some point. I will most definitely never forget my time here on the ice and I can’t wait to get home and brag about all these adventures and more!

 

Couch Surfing at the South Pole

By Laura Moon Parmeter (UWRF Undergraduate)

It’s so hard to write this blog post because it’s impossible to describe the feeling you get being at the Pole. The South Pole has been one of the most amazing places I’ve ever been. Even with it being -40 wind-chill! Everyone is so nice and has the same adventurous attitude! There are only about 150 people, which is max capacity for the station. Just passing people walking down the hall everyone has a smile on their face and is so friendly. Because of the small space that we work in there is always people to talk to. Everyone hangs out at the end of the day in the game room lounge. Doesn’t matter what your job title is, firefighter, scientist/grantee, mechanical engineer, cook, etc, all hang out together. You get to meet some amazing people!

We actually arrived to the pole on the day we were scheduled to!! With it being above 9000 feet the sudden altitude change made things difficult. Just walking up the stairs made you winded. So the first day we took it easy and just wandered around the station getting acclimated. This station is newer than McMurdo and has so many accommodations. There’s a gym and a workout center, two movie rooms (so full of movies I don’t think I could watch them all even if I wintered over), a music room, game room (with a pool table, dart board, and foosball table), a greenhouse, quite reading room (with a ton of books!), a science lab, and a sauna!

The food at the Pole is so much better than the food at McMurdo! The first day we arrived there were raspberry blondie brownies made by a lady who owners her own bakery back in the states. Another day we got filet mignon and crab legs! They even have fresh apples and oranges. I never thought I would eat so well in a cafeteria.

We were only scheduled to be at the South Pole for 5 days, so the next day we got to work! We wandered out to the IceCube lab (ICL) to set up the muon tagger equipment. We also checked out the neutron monitors, some bare inside the science lab, others fully covered and insulated sitting outside.

After getting most of our work done we changed gears a bit. We helped with the artists and writers program. Two artists want to recreate some historic photos from Antarctica, but because room space in limited at the Pole they were unable to come. So we got a GoPro camera from them and a Scott tent from the station. The tent was just a little too tall so we had to dig a trench and bury it about 3 feet. Part of the reenactment of the photos was to do interviews of the people participating. While Dr. Madsen and Robert were outside in the cold filming people, I was inside in the warmth of the station doing the interviews. This gave me the opportunity to get to know a lot of people very fast.

Before we knew it the five days were up. Our flight was scheduled to leave on Monday. Normally we need to check in our bags the day before (called “bag drag” because you literally have to drag your bag to the check in spot). But because we were leaving on Monday we had to bag drag on Saturday because on Sunday they weren’t working. We are allowed one carry-on bag to keep with us, but it has size restrictions. So the key is to try and balance how many clothes to bring but still keeping in light. The problem is you never really know when you’re leaving.

At the Pole the flights are done a little differently. First a flight will come in and drop off people and cargo. They won’t even shut of the engines before they start loading it with new cargo and people leaving the pole. They’re only on the ground for maybe an hour if everything goes as planned. So our flight came in at 11:30 pm and we all got on the plane at 12:30 am. We flew for about 45 min before they decided the weather was too bad in McMurdo so we had to turn around (what was surprising to me was that the weather was hardly ever bad at the south pole, always sunny and very little wind). We got back to the pole and had a 2 hour window were, if the weather cleared,  we would still take off. So we waited around till 3:30 am before they finally decide to call it a day. They shut off the plane’s engines… This could be bad… very very bad…! Once you shut off the engines it’s very hard to get them started again. It’s just too cold at the Pole. Also once they shut down the plane their navigation systems start to act funny and they can’t fly unless they have perfect weather conditions.

Needless to say we were stuck at the Pole until Friday. With weather delays and problems with the skyway our 5 day trip turned into 10 days. Before the boomerang flight I was ready to go. Five days were long enough for me and I was starting to get home sick. But by the end of the five extra days at the pole I didn’t want to leave!!! After we boomeranged and got back to the station our rooms were already given away. And now the station was over max capacity with 177 people. They had no more rooms for us. So they set up 10 beds in the gym. The flight crew slept in one of the movie rooms on the couches while other people found couches in the other lounges. I had the time of my life! Couch surfing pro!!!

With this extra time we got to tour a few things. We went and saw SpiceCore. We were lucky enough to show up right as they were bringing up a core. The ice was 50,000 years ago! We also got to launch a weather balloon. We got pretty friendly with the weather man Oregano who brought us frequent weather updates. We got a tour of the South Pole Telescope and also got to see the ice tunnels were the piping for the station is ran. The tunnels were really cold, about -50. At the end of that tour we got to climb a 30 foot ladder to get out of the tunnels. That was a little scary considering we just spend an hour in freezing temperatures and my hands were starting to go numb.

We got back to McMurdo and spent a few more days doing some work at Cos-Ray. We got to go inside discovery hut, which you’re only allowed to do with a guide.

 

Robert Zill at the South Pole

By Robert Zill

We made it to the South Pole! After all the troubles we’ve had up to this point with flights getting down here, it was a relief to make it to the Pole successfully on the first try (see featured photo by Delia Tosi, IceCube, UW-Madison). Upon our arrival, there were some very excited IceCubers waiting for us outside on the skiway to welcome us to the station. It was nice to know that we had friends there waiting for us! We then sat through an orientation video in one of the lounges to familiarize ourselves with the station. The main difference between the South Pole and McMurdo is that it takes significantly more resources to make water at the pole. For this reason they are stricter about things like showering. You are only allowed to take two showers per week and they can’t be more than two minutes long.

Another big difference about being at the pole is that with the exception of the experimental facilities such as IceCube, everything is located in one building. Labs, lounges, bedrooms, the galley and the gym are located in what is called the “elevated station.” It makes sense that everything is one place there because it was typically -20 degrees Fahrenheit with wind chills of less than -40 while we were there. You don’t want to go very far without gearing up in your ECW!*

Getting around to the different sites at the South Pole can be done by taking a “sled.” This is what they call their snowmobiles. There are also a variety of trailers so that you can haul equipment or more

people to the site you are visiting. Since we were not staying at the pole for very long, none of us opted to take the snowmobile training session so that we could drive, but we often found ourselves getting a ride from one of the IceCubers.

After getting acquainted with the technician who has been taking care of the neutron monitors, we went out to see the sites where they were located. There were three large and heavily insulated enclosures for the three tubes that were kept outside, identifiable by their distinctive smiley faces. There were also some bare tubes inside the station that contained helium 3, though they lacked the smiley face trademark.

The IceCube building is referred to as ICL, and we went there to set up our muon tagger and see it in action at the South Pole. There were some hiccups in the process of getting it to run smoothly and take data how we wanted it to, but after working with the electronics and consulting with Joe back at River Falls, we got it to work almost how we wanted it to. There are still a few kinks to work out. We also opted to bring back two other DAQ’s with us so that those can be upgraded before next season.
While at the South Pole, everybody was extremely friendly and nice. We got to go on some tours of other people’s projects including the South Pole Telescope group who studies the microwave cosmic background and SPICE Core who drills down into the ice and takes samples back up in order to be studied.

The final tour we did was rather interesting as well. One of the plumbers took us down below the station into what they call the “ice tunnels” where all the water and plumbing lines are located. It was about -60 degrees Fahrenheit down there, brrrrrrrr!! Every so often they have to go down with a chainsaw and widen the halls because the ice moves in and shrinks the passageways.

Trying to leave the South Pole, we again ran into troubles with the flights. We were supposed to leave for McMurdo on a Monday and we didn’t end up getting back finally until Friday because there were weather delays and an incident with another plane getting stuck on the South Pole skiway for several days. On our first attempt, a plane come picked us up and dropped off more people at the same time. We ended up boomeranging back to the pole after a short flight because it was apparent that the weather in McMurdo would not provide for a safe landing. The problem was that they had already given away our rooms to the newcomers and the station was at maximum capacity. So Laura and I became South Pole couch-surfing bums while Dr. Madsen opted to sleep in the gym where they had brought in some spare mattresses from storage. This lasted for three nights until finally another plane came to pick us up and bring us back to McMurdo. Due to the kindness and hospitality of everybody there, it was actually not a bad experience. We hung out with the stranded flight crew, the firefighters, the IceCube winter-overs, and various other people every night. Good times were had by all in the lounge playing pool and darts, listening to music and just having good conversations. The South Pole station is a very special place and I feel extremely lucky to have had the experience of spending time with all the amazing and interesting people there.
