Description
The ePIC Backward Electromagnetic Calorimeter will use PbWO₄ (PWO) crystals as the radiator material for precision electromagnetic calorimetry in the electron endcap. The PWO is a CD3-A and CD3-B long-lead item. A total of 1069 crystals were received under CD3-A and the first batches of CD3-B crystals have started arriving. This talk will present the results of the current status of PWO crystal QA and discuss the receiving quality assurance process developed for the EEEMCal PWO long-lead procurement. This will include a practical overview of our product quality, individual quality control plans, and component inspection and test plans, and how we implement them.
