Micro-pixel Avalanche Photo Diodes (MAPD)
Zecotek has developed a new compact and cost-effective photo-detector for low light detection that will phase out the bulky and expensive PMT's (photo multiplier tubes) presently used in different imaging applications such as PET, Gamma cameras and high-energy nuclear physics.
The new Micro-pixel Avalanche Photo Diodes (MAPD) detect very small signals and can be readily used for photon counting. They feature extremely high gain typical of PMT’s (~ 106) with the advantage of low operating voltage (~50 V compared to ~ 1000 V for PMT). All solid-state design makes MAPD detectors compact and insensitive to high magnetic fields. Zecotek’s detectors incorporate our break-through technology that dramatically improves linearity and allows very tight timing resolution by providing fast pulse rise time and low jitter. Together with its new scintillation material LFS, Zecotek’s photo-detectors provide a powerful platform for medical imaging applications relying on γ-ray detection, such as PET scanning, offering significant benefits to the industry.
