Iowa State University


The Iowa State University group worked with the Texas Tech University group on the HF (Hadronic Forward) calorimeters. Together, we performed simulations, beam tests, and the construction of the high voltage delivery from the power supplies to the phototubes inside the readout boxes of HF.  The high voltage distribution was a parallel dynode scheme suggested by Fairfield University and resulted in a less expensive, low power loss, and more robust system.  The cables, boards and crates were built at ISU by undergraduate physics majors.
