PERFORMANCE OF CVD DIAMOND MICROSTRIP DETECTORS UNDER PARTICLE IRRADIATION

The inherent properties of diamond make it an ideal material for detec tors in the high rate, high radiation environments near the collision point of future colliders such as the LHC. We have constructed charged particle position sensitive detectors using high quality Chemical Vap or Deposited (CVD) diamond. Using detectors with a 50 mu m strip pitch , we achieved a most probable signal-to-noise ratio of 27/1 and a posi tion resolution of 12-15 mu m. To ascertain the radiation hardness pro perties of CVD diamond, we have exposed detectors to 10 MRad Co-60, 5 X 10(14) 300 MeV pions/cm(2), 10(14) 500 MeV protons/cm(2), and 10(15) neutrons/cm(2). The results show that CVD diamond is an extremely rad iation hard material and well suited for particle detector production.
