//__2-11-08__// - Snow day...

__//2-12-08//__ - Today Dr. Loughran had us stay at school for a discussion about a possible trip to CERN for three lucky students. After the talk he held us after class to talk about voltage, threshold, and the combination of the two. He wants us to try and figure out the right combination of the two for our detectors at the lab.

__//2-13-08//__ - Today we went over to the Quarknet Center to start tweaking the voltages and threshold levels of our detector's PMTs (photo multiplier tubes). We started trying different voltages around the the area of the suggested setting that came with the detectors and we found that we get the most efficient counting from around .800 to .1000. We need to run some performance studies in order to get a more accurate level however.

__//2-14-08//__ - No class today due to a malfunction with the school's water pipe system.

__//2-15-08//__ - Today we watched a long video all about CERN and what goes on there. It peaked some interest from several students and the rest of class we talked about who would be able to go and what qualifications it would take. I can't go due to other spring break plans.
