Abstract

Three thick single crystals grown at LIMHP were investigated in regard to their thermoluminescent and electric properties like glow curve, repeatability, linearity and the current under irradiation. The crystals A, B and C showed only a very short range of the linearity after irradiation with Cs‐137 and Co‐60 gamma rays. Next, the samples were investigated regarding to their electrical properties. The samples irradiated with a Co‐60 source presented a high sensitivity to the radiation but a long saturation time. The crystal A was irradiated using a special holder at the temperature of 250 °C. The current recorded was three times higher than that at room temperature and quickly saturated.

## Abstract Diamond films were synthesized with up to 50% argon in the gas phase using high power plasma‐assisted chemical vapour deposition (PACVD). This resulted in a strong increase of the deposition rates. Polycrystalline diamond (PCD) films grown with Ar have shown a higher incorporation of sp
