SiPM 光电探测器如今广泛应用于许多应用中。对于 MAGIC 等大型望远镜或切伦科夫望远镜阵列 (CTA) 项目未来的大型望远镜 (LST)，需要几平方厘米的像素尺寸。构建并表征了模拟放大器和求和级。将大型紧凑的 SiPM 矩阵原型与相关的聚焦光学器件组装成有效面积为 3 cm2 的单片光探测器。电子器件的性能专为大气切伦科夫成像望远镜 (IACT) 应用而定制，具有快速信号和足够的信噪比 (S/N)。
SiPM photo detectors are nowadays commonly used in many applications. For large size telescopes like MAGIC or the future Large Size Telescope (LST) of the Cherenkov Telescope Array (CTA) project, a pixel size of some square centimeters is needed. An analog amplifier and sum stage was built and characterized. A large and compact SiPM matrix prototype, with the associated focusing optics, was assembled into a monolithic light detector with an active area of 3 cm2. The performance of the electronics is tailored for Imaging Atmospheric Cherenkov Telescopes (IACT) applications, with fast signal and adequate signal-to-noise (S/N) ratio.
