Front-end electronics development for TPC/MPD detector of NICA project

Time Projection Chamber (TPC) is the main tracker of the Multi-Purpose Detector (MPD) at the Joint Institute for Nuclear Research for the NICA collider (Nuclotron-based Ion Collider fAcility). The TPC Front-End Electronics (FEE) will operate with event rate up to 7 kHz. The electronics is based on the novel ASIC SAMPA, FPGAs and high-speed serial links. Each of 24 readout chambers will be served by 62 Front-End Cards (FEC) and one Readout and Control Unit (RCU). The whole system will contain 1488 FECs and 24 RCUs. The total number of registration channels is 95232. The article presents the current status of the FEE development and results of the FEC testing.
