DO's+November+5,+2007

Nov. 5, 07__** Today was a great day. First off, JK and I went to the e-lab and found simulations of what it's like to work with Cosmic Rays. A few that we did were "Hess's Ballon Ride," which was a simulation of how Hess conducted his experiment. Another was "Particle Direction" which showed on how Cosmic rays typically tend to pass throught the detectors. Ther last one was "Angle of Particle Direction" which helped show how to graph and what angle that the particle comes in. All were very helpful to giving us a basic overview of what it's like to do some real life experiments. Then after school, we met Dr. L at Notre Dame's Quarknet center and their he gave us a very detailed description of the particles are detected. To give you a short overview of how it works, a particle will pass through the detector and knock an electron loose, from there it gets directed into several barriers that when it hits one barrier, several more electrons will be knocked loose and then those knock even more loose etc. This is the stage where it passes through the PMT or Photo Multiplier Tube, which does exactly what it sounds like it does. Afterwards it tranfers all those electrons will get changed into electricity and from there that data is passed along to the computer where you can read and analyze it.

Today was nothing big, i went on the e-lab and just kind of browsed the site for new and helpful tools, sadly I found nothing groundbreaking.

Dr. Loughran asked us today to help look over some e-labs for him so we could inform the creators of any errors on the pages. I did this the whole class, and didn't have to time to do any work for Cosmic Rays.
