Summer 2011

The summer of 2011 found 4 students and two teachers doing research activities at The University of Iowa High Energy Physics group. The students and teachers built 2 devices and tested over 400 Photo-Multiplier Tubes for The Forward Calorimeter (HF) of the Compact Muon Solenoid (CMS) at the Large Hadron Collider (LHC) at CERN. These tubes were a new design and were being produced for replacement of the current tubes in HF. Each tube had to undergo dark current tests, gain tests, timing tests and linearity tests. In addition, one of every 20 tubes underwent a surface scan test, a double pulse test and an after pulse test. The team helped execute these tests and build the database for the PMTs.
