Abstract
The Multi Purpose Detector (MPD) is one of the detectors at the NICA collider and the Electromagnetic Calorimeter (ECal) is an important part of MPD. The cylindrical ECal system consists of 2400 ECal modules. In the first stage (2020–2024), Tsinghua University (THU) will produce 460 ECal modules for MPD project. This article mainly introduces the production, quality control and cosmic ray test of ECal modules in THU. The process flow, quality control standards, and testing system of ECal production have been established, which guarantees the high-quality completion of mass production on schedule. Up to now, nearly 360 modules have been manufactured, and a total of 460 modules will be produced by June 2022.
