SPMPlus: Large Area High Gain APDs
The SPMPlus is a large area version of SensL's SPM detectors incorporating an array of individual Silicon Photomultiplier (SPM) pixels tiled together using a novel packaging concept. The output of the tiles are summed together resulting in a sensor with a large active area - the first silicon alternative for Large Area PMT. The detector is packaged in a format suitable for scintillator coupling or free space / fluorescence applications and is available with appropriate interface / preamplifier electronics.
The SPMPlus is the first solid state alternative to the analog Large Area Photomultiplier Tube. It combines the high gain (106) and gain stability advantages of the PMT technology with the well appreciated benefits of size, operating voltage, robustness, reliability, magnetic insensitivity and suitability for miniaturization of silicon detectors. In addition, the novel design is tolerant to excess / ambient light.
