论文摘要
在高压下运行的时间投影室（TPC）已成为未来长基线中微子实验的关注主题。加压气体保留了大气TPC粒子检测的低动量阈值，但为中微子相互作用提供了较大的目标质量。高压操作在安全方面提出了有关超压和高压安全性的几个新挑战。提出的高压气体监测室（HPGMC）可用于研究最高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。灵活的结构使得可以交换内部检测器的一部分并测试新技术。在这项工作中，提出了HPGMC及其使用P10气体混合物的调试（$ 90 \％\ MathRM {AR} + 10 \％\ Mathrm {Ch} _4 $）。
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.
