论文摘要

Samurai Pion重建和离子跟踪器时间投影室（S $π$ RIT TPC）旨在在Riken放射性同位素光束工厂与Samurai光谱仪进行重离子碰撞的测量，并在中子富含富含核核问题的状态状态方程式上提供约束。 S $π$ RIT TPC具有50.5厘米的漂移长度和86.4 cm $ \ times $ 134.4厘米垫平面，带有12,096垫，配备了用于TPCS读取电子的通用电子设备。 S $π$ RIT TPC允许对颗粒进行出色的重建，并为跨各种能量损耗和动量提供了针对液体和其他带电颗粒的同位素分辨率。介绍了S $π$ RIT TPC的详细信息，以及基于宇宙射线和实验数据的TPC性能的讨论。

The SAMURAI Pion Reconstruction and Ion-Tracker Time Projection Chamber (S$π$RIT TPC) was designed to enable measurements of heavy ion collisions with the SAMURAI spectrometer at the RIKEN Radioactive Isotope Beam Factory and provide constraints on the Equation of State of neutron-rich nuclear matter. The S$π$RIT TPC has a 50.5 cm drift length and an 86.4 cm $\times$ 134.4 cm pad plane with 12,096 pads that are equipped with the Generic Electronics for TPCs readout electronics. The S$π$RIT TPC allows excellent reconstruction of particles and provides isotopic resolution for pions and other light charged particles across a wide range of energy losses and momenta. Details of the S$π$RIT TPC are presented, along with discussion of the TPC performance based on cosmic ray and experimental data.
