The advent of Silicon Photomultipliers (SiPMs) has significantly enhanced radiation detection instrumentation, gradually replacing Photomultiplier Tubes (PMTs) in various applications. SiPMs have notably improved performance in timing-critical applications. However, their typical analog readouts face limitations, such as high power consumption, and challenges in signal integrity associated...
Modern Silicon Photomultiplier technologies have achieved remarkable performance in several fields, ranging from medical imaging to Big Physics experiments to industrial applications. On the other hand, there are still several challenges in the SiPM and SPAD technology development. Among them, we can consider further improving the timing performance for Time-of-Flight PET and High Energy...
Digital SiPMs combine Single Photon sensitive Avalanche Diodes (SPADs) and CMOS transistors on a single piece of silicon. The direct access to the large signal of an individual firing SPAD eliminates the need for analogue amplification and allows for disabling individual noisy cells, so that the overall dark count rate is greatly reduced. A readout scheme tailored to a particular application...
A number of high energy physics and cosmology experiments use or plan to use single-photon avalanche diodes (SPADs) or SPAD based silicon photomultipliers in harsh conditions, such as cryogenic temperatures and/or high radiation environments. In this contribution, studies of the operation of SPADs, front-end electronics, and micro-lens arrays at temperatures down to liquid nitrogen will be...
