Students Build Detector Components

Students and teacher at Notre Dame spent several summers building components for the optical readout system of the hadron calorimeter on the CMS experiment. Working with technicians & scientists from the CMS HCAL project, they built optical mixers which perform the energy summation for the HCAL towers. Students assembled the mechanical structures, routed the optical fibes and performed quality assurence tests on the units they produced. The units constructed by students have been integrated into the HCAL readout boxes and mounted in place on the detectors in the CMS surface hall at CERN.

Thus far, there has been not a single failure of a decoder unit built by the ND QuarkNet group.
