- Dr. L didn't want us to go to Quarknet today beacuse he wanted to talk to the class more about the trip to CERN. After he had finished talking to the class, he held JK and I a little after school to ask us a few questions about the detectors. He had asked us if we knew that the detectors were accurate in their readings and asked us to start thinking about how to find a way to test the detectors for accuracy.

- Today at the Quarknet Center, JK and I started to fiddle around with the voltages of the PMT's (photo multiplier tubes) to get a better understanding at what settings they work at with the optimum efficiency. We figured that they work best between in the range of .800 to 1.000 vdc, but in order to be perfectly sure we still need to uplaod data when it is on all the different types of the voltage settings to see which ones come out the best.

- No class today due to the fact that a water pipe burst outside the school and they had to shut all the water off in order to fix it. Hurray!

- Dr. L showed us a 16 min. long video today about the 50th anniversary of Cern in 2003. After the video he talked to us more about the trip to Europe and asked who wanted to go and what qualifications they would have if they went.
