Barrel HCal Meeting
David Ruth: for LED test stand David needs fibers, iHCals (currently on safety pause), and 3 mm Barrel HCAL SiPMs. Since CD-3C BHCalSiPMs are listed on CD-3C, very far and anyway reserved for construction and cannot be used for testing, Eric and David will create a purchasing plan to order about two dozen (~24) units to cover testing needs and minimum orders. Additionally, Norbert secured funding for CALOROC development, with 50 boards ordered for late August delivery—most going to New Hampshire and Georgia, while 1 to 2 will be sent to David.
Jan Vanek: Jan presented neutron calibration follow-up data showing inconsistencies in the BECal, where sum cluster energy is sometimes smaller than or equal to zero compared to hits and BECal is the case for the issues observed last update. Meanwhile, the BHCal showed energies significantly higher than generated, reaching up to 7 GeV for a 1 GeV neutron.
