Abstract: The Solenoidal Tracker at RHIC (STAR) is a detector being
built at Brookhaven National Laboratory that will search for quark-gluon
plasma signatures in heavy ion collisions. A quark-gluon plasma is
a phase of matter where quarks and gluons, which are normally confined
to individual protons and neutrons, mix with quarks and gluons of neighboring
protons and neutrons. This phase of matter is theorized to have existed
for less than one millisecond in the beginnings of the universe.
The main detector of the STAR experiment, the Time Projection Chamber (TPC),
recently came online for hardware and software tests. Test data has
already been collected from cosmic ray tests of the TPC. I will present
an analysis of pedestal voltage variations in the pads located at the endcaps
of the TPC. This analysis will help to identify defects in the electronic
readout system and can be used to calibrate the detector.
