Betabox: a beta particle imaging system based on a position sensitive avalanche photodiode.
A beta camera has been developed that allows planar imaging of the spatial and temporal distribution of beta particles using a 14 × 14 mm(2) position sensitive avalanche photodiode (PSAPD). This camera system, which we call Betabox, can be directly coupled to microfluidic chips designed for cell incubation or other biological applications. Betabox allows for imaging the cellular uptake of molec...
متن کاملPerformance measurements of a depth-encoding PET detector module based on position-sensitive avalanche photodiode read-out.
We are developing a high-resolution, high-efficiency positron emission tomography (PET) detector module with depth of interaction (DOI) capability based on a lutetium oxyorthosilicate (LSO) scintillator array coupled at both ends to position-sensitive avalanche photodiodes (PSAPDs). In this paper we present the DOI resolution, energy resolution and timing resolution results for complete detecto...
متن کاملAvalanche photodiode A User Guide
Introduction Avalanche photodiode detectors (APD) have and will continue to be used in many diverse applications such as laser range finders, data communications or photon correlation studies. This paper discusses APD structures, critical performance parameter and excess noise factor. For low-light detection in the 200to 1150-nm range, the designer has three basic detector choices the silicon P...
متن کاملPosition-Sensitive Avalanche Photodiodes for Gamma-Ray Imaging
In this paper, we report on the investigation of silicon avalanche photodiodes (APDs) for high-energy photon imaging applications. This includes a new APD design that provides X-ray and -ray imaging with significant reduction in electronic readout requirements. This new APD design, referred to as position-sensitive avalanche photodiode (PSAPD), involves charge sharing amongst the electrodes tha...
متن کاملThe Capacity of Avalanche Photodiode-Detected Pulse-Position Modulation
The capacity is determined for an optical channel employing Pulse Position Modulation (PPM) and an Avalanche PhotoDiode (APD) detector. This channel is different from the usual optical channel in that the detector output is characterized by a Webb-plus-Gaussian distribution, not a Poisson distribution. The capacity is expressed as a function of the PPM order, slot width, laser dead time, averag...
