Abstract

The article is aimed at describing the development status, design features and advanced version of the TPC data readout system.

The TPC is placed in the middle of the Multi-Purpose Detector and provides tracking and identification of charged particles in the pseudorapidity range |η| < 1.2.

Tracks in the TPC are registered by 24 readout chambers that are placed at both end-caps of the sensitive volume. The readout system of each chamber consists of the front-end cards (FECs, 62 per chamber) and a readout control unit (RCU). FECs collect signals directly from the chamber pads, amplify them, digitize, process and transfer it to the RCU.

The design concept and improvement have been motivated by NICA project requirements for a trigger rate up to 7 kHz with mean tracks multiplicity of 300 tracks (maximum multiplicity – up to 1000 tracks) and by the requirement of TPC end-caps transparency about X/Xo = (15÷20)%.
