摘要
NEXT-100 目前正在西班牙比利牛斯山的 Canfranc 地下实验室（Laboratorio Subterr\'aneo de Canfranc）建造，它将使用装有 100 kg 氙气的高压气态时间投影室（TPC）来搜寻无中微子双贝塔衰变。电荷放大通过电致发光（EL）实现，该过程是在高电场区域中加速电子，引起与初始电荷成正比的介质次级闪烁。NEXT-100 的 EL 区和阴极区由直径 1 m 的绷紧六边形网格制成。本文描述了 NEXT-100 这些部件的设计、表征与安装。对电场进行了模拟，以在各种 EL 区对齐和旋转下对探测器中产生的电离电子的漂移和放大建模。在空气中静电击穿电压的测量表征了高压条件下的性能并确定了击穿点。网格的静电偏转被量化并拟合到一个基于第一性原理的力学模型。测量是使用独立的测试 EL 区以及在安装到探测器之前使用 NEXT-100 的 EL 区进行的。最后，我们描述了在 2023 年夏季部署后安装于 NEXT-100 中的这些部件。
