Time-projection chamber for Multi-Purpose Detector of NICA project at JINR

Abstract

Time Projection Chamber (TPC) is the main tracker of the Multi-Purpose Detector (MPD). The detector will operate at one of the beam interaction points of collider NICA (Nuclotron-based Ion Collider fAcility) [1] and it is optimized to investigate heavy-ion collisions in the energy range from 4 to 11 GeV/nuclon. At the average luminosity of 1027 cm−2⋅s−1 for gold collisions at 9 GeV/nuclon the event rate will reach up to 7 kHz. The emphasis of this paper is made on the TPC front end electronics based on novel ASIC chips, other systems of the TPC are shortly described.
