Cryogenic Single Chip Electron Spin Resonance Detectors

Methods based on the electron spin resonance (ESR) phenomenon are used to study paramagnetic systems at temperatures that ranges from 1000 to below 1 K. Commercially available spectrometers achieve spin sensitivities in the order of 1010 spins/ p Hz at room temperature on sample with volumes in the order of few μl. This results can be improved by cooling the system at cryogenic temperatures, wh...

Advances in gas avalanche radiation detectors for biomedical applications

Gas avalanche detectors are instruments of choice for radiation detection and localization in numerous "elds of basic and applied research. Recent advances in detection techniques, involving multiplication and detection of single or a few charges deposited in gas media, or emitted from solid converters into gas, are described. The properties of radiation converters and associated advanced gas m...

III-Nitride Based Avalanche Photo Detectors

Research into III-Nitride based avalanche photodiodes (APDs) is motivated by the need for high sensitivity ultraviolet (UV) detectors in numerous civilian and military applications. By designing III-Nitride photodetectors that utilize low-noise impact ionization high internal gain can be realized—GaN APDs operating in Geiger mode can achieve gains exceeding 1×10. Thus with careful design, it be...
