Alpha particle detector based on micropixel avalanche photodiodes

Geiger-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 ...

Improved x-ray detection and particle identification with avalanche photodiodes.

Avalanche photodiodes are commonly used as detectors for low energy x-rays. In this work, we report on a fitting technique used to account for different detector responses resulting from photoabsorption in the various avalanche photodiode layers. The use of this technique results in an improvement of the energy resolution at 8.2 keV by up to a factor of 2 and corrects the timing information by ...

Flexible silicon-based alpha-particle detector

Solar-blind avalanche photodiodes

There is a need for semiconductor based UV photodetectors to support avalanche gain in order to realize better performance and more effectively compete with existing photomultiplier tubes. However, there are numerous technical issues associated with the realization of high-quality solar-blind avalanche photodiodes (APDs). In this paper, APDs operating at 280 nm, within the solar-blind region of...

Avalanche Photodiodes: A User's Guide

Avalanche photodiode detectors have and will continue to be used in many diverse applications such as laser range finders and photon correlation studies. This paper discusses APD structures, critical performance parameters and the excess noise factor.
