Synthetic Diamond for use in Radiation detector
Synthetic diamond radiation detectors are used in high energy physics, ionising radiation and deep ultraviolet monitoring.
Element Six has developed a range of electronic grade CVD diamond material (single crystal and polycrystalline plates) that can be used in a variety of demanding radiation detection applications including high energy physics, medical dosimetry in radiotherapy, and neutron detection for radiation level monitoring in civil nuclear, and homeland security applications as well as geophysical prospecting.
The synthetic diamond used in radiation detector is manufactured using a process called chemical vapour deposition (CVD). This process takes a mixture of gases and forms plasma with the extreme high temperature of a sun spot to allow carbon to precipitate onto a substrate layer as synthetic diamond with ultra-high levels of purity.
This level of purity enables synthetic diamond to become an ideal radiation detector material thanks to its properties that include:
- a very low leakage current with negligible temperature dependence
- a fast signal response
- a vastly improved radiation hardness
- a reduction of leakage-current compared to silicon, the material traditionally used for detectors
For many clients, synthetic diamond has been demonstrated to be the most robust sensor material available which can withstand the harsh, high radiation environment and react almost instantaneously to protect the advanced measurement systems. For example, Element Six’s synthetic diamond has been an integral part of the CERN LHC (Large Hadron Collider) CMS (Compact Muon Solenoid) and ATLAS Beam Condition Monitoring Systems, used in the recent experiments which revealed the discovery of a new particle consistent with Higgs boson.
