Method for mapping charge pulses in semiconductor radiation detectors

Semiconductor Detectors in Radiation Medicine:

Semiconductor radiation detectors play an important role in radiation instrumentation. They have many advantages due to their small size, outstanding energy resolution in nuclear spectroscopy, easy pixilation for high spatial resolution and ability of integration with readout electronics. Advancement in microelectronic industry made silicon one of the most popular material for radiation detecto...

New materials for radiation hard semiconductor detectors

We present a review of the current status of research into new semiconductor materials for use as particle tracking detectors in very high radiation environments. This work is carried out within the framework of the CERN RD50 collaboration, which is investigating detector technologies suitable for operation at the proposed Super-LHC facility (SLHC). Tracking detectors operating at the SLHC in t...

Charge Transport Properties of CdMnTe Radiation Detectors

Semiconductor gamma and X-ray detectors are finding increase use in medicine, industry, astronomy and national security. Conventional semiconductors consist mainly of germanium and silicon. Their use has however become marginalised in an increasing number of applications due to their physical limitations such as low detection efficiency and the need for bulky cryogenics. Detectors based on wide...

Charge transport in arrays of semiconductor gamma-ray detectors.

We analyze the effects of electrode size on performance of arrays of semiconductor gamma-ray detectors, especially when there is significant charge trapping. With large electrodes, motions of holes and electrons are of equal importance, but when the positive electrode is segmented into an array of small elements the contributions of holes to the output, and hence the effects of hole trapping, a...
