摘要：

时间投影室（TPC）可用于通过将光子转换成e+e-对来测量伽马射线的偏振，其具有在MeV-GeV能量范围内的优异的角度精度和灵敏度。气密性氩偏振仪（HARPO）原型的建立，以证明这一概念。它最近在日本的NewSUBARU设施的偏振光子束中进行了测试。我们提出了这个数据采集运行，它证明了HARPO TPC的出色性能。

英文摘要：

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.
