时间投影室 (TPC) 可用于通过将光子转换为 e+e− 对来测量 MeV-GeV 能量范围内的伽马射线偏振，具有出色的角度精度和灵敏度。密封 ARgon 偏振计 (HARPO) 原型就是为了演示这一概念而建造的。最近在日本 NewSUBARU 工厂进行了偏振光子束测试。我们展示了这次数据采集运行，它展示了 HARPO TPC 的卓越性能。
A time projection chamber (TPC) can be used to measure the polarization of gamma rays with excellent angular precision and sensitivity in the MeV-GeV energy range through the conversion of photons to e+e− pairs. The Hermetic ARgon POlarimeter (HARPO) prototype was built to demonstrate this concept. It was recently tested in the polarized photon beam at the NewSUBARU facility in Japan. We present this data-taking run, which demonstrated the excellent performance of the HARPO TPC.
