标题： High Voltage Delivery and Distribution for the NEXT-100 Time Projection Chamber

摘要： 大型液体和气体时间投影室（TPC）实现中的一个关键因素是高压的传输和分布到探测器内部及其周围。此类实验需要约数十千伏的电压以使电子漂移达米级距离。本文介绍了NEXT-100实验的阴极馈通设计及高压通过场笼的分布，NEXT-100是一个地下TPC，将用于搜寻无中微子双贝塔衰变$0\nu\beta\beta$。该馈通已被证明能够承受高达20巴的压力，并能维持高达-65千伏的电压，且TPC在其设计的高电压下稳定运行。该系统是在严格的放射性纯度预算限制内实现的，并且现在正用于执行一系列敏感的双贝塔衰变分析。 显示英文摘要

摘要： A critical element in the realization of large liquid and gas time projection chambers (TPCs) is the delivery and distribution of high voltages into and around the detector. Such experiments require of order tens of kilovolts to enable electron drift over meter-scale distances. This paper describes the design and operation of the cathode feedthrough and high voltage distribution through the field cage of the NEXT-100 experiment, an underground TPC that will search for neutrinoless double beta decay $0\nu\beta\beta$. The feedthrough has been demonstrated to hold pressures up to 20~bar and sustain voltages as high as -65~kV, and the TPC is operating stably at its design high voltages. The system has been realized within the constraints of a stringent radiopurity budget and is now being used to execute a suite of sensitive double beta decay analyses.
