Status and prospects of TPC prototype using the UV laser mimic tracks

Abstract

To meet the high precision physical goals in the future e + e − circular collider (CEPC), the high resolution tracker detector for the particle track reconstruction (¡100μ m) and particle identification are required. Time Projection Chamber (TPC) is one of the main concept option of the central tracker detector. On behalf of the track detector subgroup in CEPC, the status and update R&D results of TPC module and prototype for the specific requirements will be presented in this article. TPC module will could suppress the ions in chamber continuously running in the different gains (2000-5000) and T2K mixture gases, and TPC prototype with Micro-pattern Gaseous Detector (MPGD) detector module integrated the narrow laser mimic tracks system. the update results of the spatial resolution, particles identified (dE/dx) were been investigated. In this TPC prototype, the precision drift time of the different laser mimic tracks ionized primary electrons in the specific operation working gases were recorded. Some considerations of the low power consumption readout requirements will be given according to the pad TPC detector operating at the high luminosity Z pole at CEPC.
