Philip Hamacher-Baumann, Stefan Roth, Thomas Radermacher, Nick Thamm

摘要:

高压时间投影室(TPC)已成为未来长基线中微子实验的研究热点。对于大气TPC的粒子探测,加压气体保持了低的动量阈值,但在相同体积下为中微子相互作用提供了更大的目标质量。在高压下操作在有关过压和高压安全的安全方面提出了若干新的挑战。所介绍的高压气体监测室(HPGMC)可用于研究高达10 bar的各种漂移气体混合物的适用性和$\sim$ 3000 V/cm的最大场。灵活的结构使得更换内部探测器部件和测试新技术成为可能。在这项工作中,一个HPGMC的建设和使用P10气体混合物($90 \% \mathrm{Ar} + 10 \% \mathrm{CH}_4$)的调试。

英文摘要:

Time Projection Chambers (TPCs) operated at high pressure have become a topic of interest for future long baseline neutrino experiments. Pressurized gas retains the low momentum threshold for particle detection of atmospheric TPCs, but offers a larger target mass for neutrino interactions at the same volume. Operation at high pressure poses several new challenges in safety aspects regarding overpressure and high voltage safety. The presented High Pressure Gas Monitoring Chamber (HPGMC) can be used to study the suitability of various drift gas mixtures up to 10 bar and a maximum field of $\sim$3000 V/cm . A flexible construction makes it possible to exchange parts of the inner detector and to test new technologies. In this work, the construction of a HPGMC and its commissioning using the P10 gas mixture ($90 \% \mathrm{Ar} + 10 \% \mathrm{CH}_4$) are presented.
