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

摘要： 在实现大型液体和气体时间投影室（TPCs）中，关键要素是将高电压输送并分布到探测器内部和周围。 此类实验需要大约十千伏的电压，以使电子在米级距离内漂移。 本文描述了NEXT-100实验阴极穿通装置和通过场笼的高电压分布的设计与操作，这是一个地下TPC，将用于搜索无中微子双β衰变$0\nu\beta\beta$。 该穿通装置已证明能够承受高达20~bar的压力并维持高达-65~kV的电压，TPC目前在其设计高电压下稳定运行。 该系统在严格的放射纯度预算限制内实现，并现在被用于执行一系列灵敏的双β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.
