Anna’s 6th Week in Europe

Editor’s Note: Is Rami having any fun at all, or is he stuck in the lab?

Hello!

I can’t believe it is already the end of July. This summer is flying by, but I guess we all know what they say… time flies when you’re having fun.

 

Progress has been made on the ARA station fitting and calibration. Thomas and I have incorporated a ray trace correction (as I talked about last week) successfully. On Wednesday I presented to the group about the progress we have made. Now next week we plan to test the reconstruction on some data that was taken from different locations surrounding the station with a pulser above the ice. Hopefully these results further prove we have successfully attained station coordinates.

 

This weekend I had my first visitors in Beglium! My cousin from Ireland and his girlfriend came to stay at our house. On Friday we went to Bruges for the morning and then traveled to Gent for a music festival that afternoon. On Saturday we traveled to Dinant and toured the city. In the evening we explored downtown Brussels. Brussels is so great in the dark with the whole city lit up. the picture below is a view from nearby the Parliament building looking down to the city. Sunday we spent the day at the Brussels Park and ate wonderful food downtown. It was so much fun sharing with people the country I call home temporarily.

 

Thanks for reading!

Week Five in Brussels

Bonjour!

Week 5 has come and gone. This summer is going by way too fast. This week I started to wrap up the calibration and station fitting. I have been trying different ways to correct the timings of the hit when I input them into the reconstruction method. The reason for this is that we don’t take into account ray tracing. Ray tracing corrects  an effect on the radio pulse’s path because of the ice properties. It causes a curve in the path which would make the time from the pulse sent (either from the calibration pulses or a neutrino interaction in the ice) to the time the detector gets hit different than if it had a straight line path. Our reconstruction assumes there is a straight line path, so we have been trying to change this.

 

Over the weekend I traveled to DInant, Belgium. It is a lovely city south east of Brussels. I stayed at a hostel owned by a physicist and his wife that are from Michigan. Such a small world! On Saturday I did a little hiking and site seeing and on Sunday I kayaked down the river. It was a very relaxing weekend in a beautiful city. The picture above is the view from the room I stayed in at the hostel.

 

On monday Rami and I had the day off because it was a national holiday. We went downtown to the festivities. There was a fair and music throughout the city centre. It was cool to see the traditions of another city on a holiday. The holiday celebrates Beglium’s first king, Leopold. The royal family makes an appearance and the whole city awaits eagerly to see their royal family.
