Overview of silicon detectors

Abstract

An overview of the ingredients and layout of the most commonly used Si-detectors is given. Their performance is illustrated by the results of some selected experiments. The challenges in the high radiation environment of the LHC, and the changes in signal collection after heavy irradiation are reviewed. Possible future solutions in ultra high radiation environments are briefly discussed. r

Evaluation of solid-state detectors in medical imaging with fuzzy PROMETHEE

“…A disadvantage of silicon detectors is that even though it can operate at room temperature, it still heats up and requires sophisticated cooling mechanisms in order to reduce the leakage of currents. Silicon detectors are also susceptible to degradation after a period of time due to the effects of radiation [16].…”

Charge collection inefficiencies induced by intense /sup 12/C bombardment of SSB detectors

“…More recently, the challenges in the harsh radiation environment of the Large Hadron Collider (LHC) at the Centre Européen pour la Recherche Nucléaire (CERN), France, have triggered a good deal of investigations on this subject, as reviewed for example in [17]. Bulk properties such as the variation of the electric characteristics of different Silicon detectors after heavy irradiation have been well characterized [17], [18], and their effects on CCIs have been studied. It has been found, for example, that the detector-resistivity changes for fluences above some threshold value [15] and the bulk current increases linearly with the fluence [17].…”
