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.

MPD TPC 状态

在 JINR 研究热和致密重子物质的科学计划的框架内，正在实现基于 Nuclotron-M 的新型加速器复合离子对撞机 fAcility (NICA)。在 NICA 预见到两个探测器的两个交互点。这些检测器之一，多用途检测器 (MPD)，针对重离子碰撞研究进行了优化，光度高达 1027 cm-2 s-1，离子高达 Au79+。时间投影室 (TPC) 是 MPD 中央枪管的主要跟踪探测器。它是一种众所周知的检测器，用于对高多重事件进行 3 维跟踪和粒子识别。MPD的概念布局、TPC设计及其参数，
