Today I arrived at Quarknet at 3:45. As I arrived I saw Dr. L, and then I went into the lab. Once I entered the lab I attempted to use my laptop to access the internet, because I have all of the proper software, but I could not access the internet. Once I discovered this, I got onto a desktop and installed all of the software to run many eyes. While this was installing I read Alex Jones' logbook, to get an idea of what the group did yesterday. According to Alex, the group looked at Many Eyes and looked at specific data points, on which could be a Cosmic Ray. The points which we were looking at were mostly on a horizontal axis, in a straight line. Alex also wrote about how they could view multiple data points at once, which I thought was an interesting technique. I attempted this technique and I selected points that were within the 0.0 and the 0.2 eta range that Alex mentioned in his logbook. These were some of the points I selected. These points, I believe show what could be a cosmic ray, traveling through the detector, encountering many different particles. This image is further evidence, as to what I believe could be a cosmic ray. It is shown as a yellow band of dots forming what seems to be a seemingly straight line. These points when viewed at other angles or with different data sets, show similar event displays, such as when you make the axis phi or eta. This shows phi 1 and Mass. The majority of the particles which could be in the cosmic ray appear near the bottom of the chart. This graph shows the majority of the particles forming what could be the cosmic ray near the top. This graph represents phi 2 and mass. These graphs give evidence to the groups theory that a cosmic ray had passed through the detector. After reading over the logbooks of Alex, Grace, and John, I felt that I had a reasonable understanding of eta and phi, as it pertains to finding what could be cosmic rays. Once I had finished reading over the logbooks and making final additions to my own, it was time to leave Quarknet, at 5:30.
