Radiation tolerance of diamond detectors

Electromagnetic Radiation Hardness of Diamond Detectors

The behavior of artificially grown CVD diamond films under intense electromagnetic radiation has been studied. The properties of irradiated diamond samples have been investigated using the method of thermally stimulated current and by studying their charge collection properties. Diamonds have been found to remain unaffected after doses of 6.8 MGy of 10 keV photons and 10 MGy of MeV-range photon...

Diamond Detectors as Beam Monitors

CVD diamond particle detectors are already in use in the CERN experiments ATLAS, CMS, LHCb and ALICE and at various particle accelerator laboratories in USA and Japan. This is a proven technology with high radiation tolerance and very fast signal read-out [1]. It can be used for measuring single-particles as well as for high-intensity particle cascades, for timing measurements on the nanosecond...

Development of Single-Crystal CVD-Diamond Detectors

Single-Crystal CVD-Diamond Detectors (SC-DD) of ~ 300μm thickness have been tested in Cave A with proton beams of Ep > 1AGeV as start detectors for minimum ionizing particles. Fast charge-sensitive amplifiers developed at GSI and Bucharest were used. At particle rates up to 1MHz, stable operation and detection efficiency of ~100% are observed. The measured time resolution of σ ≥ 330ps is not sa...

Characterisation of Single-Crystal CVD-Diamond Detectors

Recently, the quality of intrinsic CVD Diamond (CVD-D) has tremendously been improved. The replacement of the previous used silicon substrates for growth by ultra-pure HPHT Single-Crystal (SC) {100}-oriented diamond provides homo-epitaxial grown material almost free of structural defects. Nevertheless, all substrates nominally {100}oriented show a certain amount of off-angle declination from th...
