In order to further the understanding of the evolution of the Universe and Quark Gluon Plasma, the detector must send non-defective data to be analyzed. Thus, the performance of the PHOBOS silicon detector is of utmost importance to the experiment. It is imperative that we know the condition of the silicon sub detectors. The programs written in this research do exactly that; validate the performance through average noise values of the sub detectors. Through these programs, it is evident if something were to go wrong. If the detector suddenly had radiation damage due to higher luminosity runs at RHIC, or some other problems, the shift crew would be made aware of the problem right away. This allows for quick validation of the performance of the detector before more lengthy analyses down the road. The result is a graphical program that displays the average noise values of the seven sub detectors, and would show increased noise values if there were any problems. If the noise increased, the PHOBOS collaboration would be immediately aware of the situation and could deal with it appropriately. The work on the noise of the detector aided in the processing of data for the analysis.

In addition to my work on detector performance, I was lucky enough to be working with the Phobos detector as it was first obtaining data. I contributed to obtaining the first collision measurements with Phobos in the summer of 2001.
