我们开发了含有类金刚石碳 (DLC) 的电阻 THGEM (RTGEM) 薄膜，这是一种具有可调电阻率的坚固电阻材料。 RTGEM 薄膜是通过磁控溅射在 PCB 上涂覆 DLC 层，然后机械钻孔来制造的。成功制作了不同配置的RTGEM探测器原型，敏感面积范围从5×5 cm2到20×100 cm2。为了实现更高的增益，通过电阻 DLC 层将单面 RTGEM 耦合到阳极 PCB，引入了电阻井 (RWELL) 探测器。与传统的金属电极 THGEM 相比，RTGEM 制造工艺更加简单、高效，适合大规模生产。电阻材料可以限制高气体增益时发生的放电能量，使探测器更加坚固。单级 RTGEM 探测器实现了 >103 的增益，并表现出良好的长期增益稳定性。大面积 RTGEM 探测器（有效面积：20 × 100 cm2）具有良好的增益均匀性（∼12%）。 RWELL 探测器实现了 >8 × 103 的增益。本文介绍了详细的制造工艺和性能研究结果。
We developed resistive THGEM (RTGEM) films with diamond-like carbon (DLC), a robust resistive material with adjustable resistivity. The RTGEM films were manufactured by coating DLC layers on PCB via magnetron sputtering and then mechanically drilling holes. RTGEM detector prototypes with different configurations with sensitive area ranging from 5 × 5 cm2 to 20 × 100 cm2 were successfully fabricated. To achieve higher gain, resistive well (RWELL) detectors were introduced by coupling single-faced RTGEM to anode PCB via resistive DLC layers. The RTGEM manufacturing process is simpler and efficient compared with the conventional THGEM with metallic electrodes, making it suitable for large-scale production. The resistive material can limit the energy of discharges occurring at high gas gains, making the detectors more robust. The single-stage RTGEM detectors achieved gains >103 and demonstrated good long-term gain stability. A large-area RTGEM detector (active area: 20 × 100 cm2) had good gain uniformity (∼12%). RWELL detectors achieved gains >8 × 103. Detailed fabrication process and performance study results are presented in this article.
