Description
Pixelated Geiger-mode avalanche photo-diodes also called silicon photo-multipliers (SiPMs) are replacing traditional vacuum photo-multiplier tubes (PMTs) in numerous applications in subatomic physics, medical imaging and condensed matter. They have several advantages being insensitive to magnetic field, having higher efficiency, more uniform gain, and being more compact. However, they still cannot compete with PMTs for application requiring large areas of photo-detection at room temperature. We will describe their characteristics and performances and show a few specific applications in particle physics, condensed matter and medical imaging.
