日本质子加速器研究综合体（J-PARC）开发了一种新的时间投影室（TPC），用于使用脉冲冷中子散裂源进行中子寿命测量。管理来自自然源和束放射性的大量背景事件是这种测量的一个具有挑战性的方面。为了克服这个问题，开发的TPC具有前所未有的功能，例如在支撑结构中使用聚醚醚酮板，以及覆盖有6Li富集瓦片的内表面以吸收异常中子。在本文中，新的TPC的设计和性能的详细报告。
A new time projection chamber (TPC) was developed for neutron lifetime measurement using a pulsed cold neutron spallation source at the Japan Proton Accelerator Research Complex (J-PARC). Managing considerable background events from natural sources and the beam radioactivity is a challenging aspect of this measurement. To overcome this problem, the developed TPC has unprecedented features such as the use of polyether-ether-ketone plates in the support structure and internal surfaces covered with6Li-enriched tiles to absorb outlier neutrons. In this paper, the design and performance of the new TPC are reported in detail.
