在过去几年中，人们做出了许多努力来开发与硅光电倍增管 (SiPM) 相关的新技术。这些光电传感器由一系列相同的雪崩光电二极管组成，这些二极管在盖革模式下运行并并联连接到单个输出。意大利核物理研究所 (INFN) 参与了意大利的 Progetto Premiale Telescopi CHErenkov 研发计划 (TECHE.it)，为基于 SiPM 的相机开发光电传感器，该相机将成为切伦科夫望远镜阵列 (CTA) 天文台的一部分。在此框架中，正在对适合检测蓝色和近紫外波长区域切伦科夫光的创新设备进行测试，即所谓的近紫外硅光电倍增管（NUV SiPM）。对布鲁诺凯斯勒基金会 (FBK) 生产的光电传感器的测试显示出良好的性能：低工作电压、能够检测低至单光子的极低强度光以及 390-410 nm 范围内的高光电检测效率 (PDE)。特别是，所开发的器件是基于 30 μm×30 μm 和 6 mm×6 mm 面积的微单元的高密度 NUV-SiPM (NUV-HD SiPM)。已经对该探测器进行了单池配置和矩阵排列的测试。与此同时，基于针对新型 NUV-HD SIPM 优化的波形采样技术的前端电子器件正在研究和开发中。
In the last few years a number of efforts have been undertaken to develop new technology related to Silicon Photomultipliers (SiPMs). These photosensors consist of an array of identical Avalanche Photodiodes operating in Geiger mode and connected in parallel to a single output. The Italian Institute of Nuclear Physics (INFN) is involved in the R&D program Progetto Premiale Telescopi CHErenkov made in Italy (TECHE.it) to develop photosensors for a SiPM based camera that will be part of the Cherenkov Telescope Array (CTA) observatory. In this framework tests are ongoing on innovative devices suitable to detect Cherenkov light in the blue and near-UV wavelength region, the so-called Near Ultra-Violet Silicon Photomultipliers (NUV SiPMs). The tests on photosensors produced by Fondazione Bruno Kessler (FBK) are revealing promising performance: low operating voltage, capability to detect very low intensity light down to a single photon and high Photo Detection Efficiency (PDE) in the range 390–410 nm. In particular the developed device is a High Density NUV-SiPM (NUV-HD SiPM) based on a micro-cell of 30 μm×30 μm and 6 mm×6 mm area. Tests on this detector in single-cell configuration and in a matrix arrangement have been done. At the same time front-end electronics based on the waveform sampling technique optimized for the new NUV-HD SIPMs is under study and development.
