论文摘要
2022年将在RHIC安装的SPHENIX探测器旨在精确测量重离子碰撞中的喷气机，喷射相关和Dilepton对。考虑到这些测量值，Sphenix将采用紧凑的TPC覆盖20厘米<r <78 cm和|η| <1.1作为中央跟踪器。 TPC利用优化的AR-CF4气体混合物，锯齿形读数垫，1.4 T螺线管和改良的SAMPA芯片进行流式读数，TPC将提供足够的位置分辨率，足以在高事件速率环境中测量目标可观察力。将讨论TPC的设计，以及测试光束数据和对EIC的潜在适用性
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 Ar-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 design of the TPC will be discussed, as well as test beam data and potential applicability to the EIC
