Characterization of a Geiger-mode Avalanche Photodiode
A 32 by 32 array of packaged 100 μm Geiger-mode avalanche photodiodes were tested and characterized. A breakdown voltage of 32 V was measured; at or just above this voltage is where the device should be biased in order to operate in Geiger-mode. The ideal region of the forward biased IV curve resulted in an ideality factor of 1.0 and no recombination/generation region. In addition, IDL code was...
متن کاملThe Blocking Probability of Geiger-Mode Avalanche Photo-diodes
When a photon is detected by a Geiger-mode avalanche photo-diode (GMAPD), the detector is rendered inactive, or blocked, for a certain period of time. In this paper we derive the blocking probability for a GMAPD whose input is either an unmodulated, Bernoulli modulated or pulse-position-modulated (PPM) Poisson process. We demonstrate how the PPM and Bernoulli cases differ, illustrating that the...
متن کاملGeiger-mode avalanche-photodiodes as readout for the CALIFA detector
The CALIFA spectrometer, which surrounds the RB target, will be used for detection of gamma-rays and highenergy protons. Of particular interest for this detector the energy resolution and its dependence on different configurations and components has to be studied. Cs(Tl) crystals with photomultiplier tubes (PMT) or avalanchephotodiodes (APD) readout as well as LaBr3(Ce) so far with PMT readout ...
متن کاملCharacterisation of Geiger-mode avalanche photodiodes for medical imaging applications
Recently developed multipixel Geiger-mode avalanche photodiodes (G-APDs) are very promising candidates for the detection of light in medical imaging instruments (e.g. positron emission tomography) as well as in high-energy physics experiments and astrophysical applications. G-APDs are especially well suited for morpho-functional imaging (multimodality PET/CT, SPECT/CT, PET/MRI, SPECT/MRI). G-AP...
متن کاملGeiger-Mode Avalanche Photodiodes in Standard CMOS Technologies
Photodiodes are the simplest but most versatile semiconductor optoelectronic devices. They can be used for direct detection of light, of soft X and gamma rays, and of particles such as electrons or neutrons. For many years, the sensors of choice for most research and industrial applications needing photon counting or timing have been vacuum-based devices such as Photo-Multiplier Tubes, PMT, and...
