MPD TPC status

Abstract

In the frame of the JINR scientific program on study of hot and dense baryonic matter a new accelerator complex Ion Collider fAcility (NICA) based on the Nuclotron-M is under realization. Two interaction points are foreseen at NICA for two detectors. One of these detectors, the Multi-Purpose Detector (MPD), is optimized for investigations of heavy-ion collisionsat a luminosity up to 1027 cm−2 s−1 for ions up to Au79+. The Time-Projection Chamber (TPC) is the main tracking detector of the MPD central barrel. It is a well-known detector for 3-dimensional tracking and particle identification for high multiplicity events. The conceptual layout of MPD, TPC design and it's parameters, the current status of the readout based on multiwire proportional chamber (MWPC) and readout electronics based on SAMPA chip as well as the status of TPC subsystems are presented.
