Iowa Test Plans for ESTB B. Bilki, Y. Onel University Of Iowa
Digital Hadron Calorimeter (DHCAL) Tests • Development of low-resistivity glass is underway in collaboration with the COE College, Cedar Rapids, Iowa. • Might need to test RPCs with different glass samples in beam. • Variable particle rate over 50 – 2000 Hz/cm2 is needed. • Secondary Emission (SE) Calorimetry Tests • In an SE detector module, secondary electrons are generated from an SE cathode when charged hadron or electromagnetic shower particles penetrate the SE sampling module placed between absorber materials in calorimeters. • A prototype SE module is being built with alternating layers of multianode PMT arrays and steel absorbers (first stage involves testing a single layer with an absorber of variable thickness). • Dual Readout/Crystal Calorimetry • Different crystal samples with different readouts. • Test for the time and spatial development of scintillation and Čerenkov light. • Readout with SiPMs and PMTs directly coupled to the crystals. • Test for different crystal properties (surface finish, wrapping, etc.) • Precise beam position measurement is needed (wire chambers, etc.)
