Abstract

Abstract : The sPHENIX detector to be installed at RHIC in 2022 is designed to precisely measure jets, jet correlations, and dilepton pairs in heavy-ion collisions. With these measurements in mind, sPHENIX will employ a compact TPC covering 20cm < r < 78 cm and | η | < 1.1 as the central tracker. Utilizing an optimized Ne-CF4 gas mixture, zigzag readout pads, a 1.4 T solenoid, and a modified SAMPA chip for streaming readout, the TPC will provide a position resolution sufficient for measuring target observables in a high event rate environment. The sPHENIX TPC, with some modifications, could be a mid-rapidity tracking component in a day-one Electron-Ion Collider (EIC) detector. The design of the TPC will be discussed, as well as test beam data and applicability to the EIC.
