Abstract
The paper reviews measurements of the radiation tolerance of CVD diamond fo r irradiation with 24 GeV/c protons, 300 MeV/c pions and 1 MeV neutrons. Fo r proton and neutron irradiation, the measured charge signal spectrum is co mpared with the spectrum calculated by a model. Irradiation by particles ca uses radiation damage leading; to a decrease of the charge signal. However, both the measurements and the outcome from the model shows that for tracke r applications this drawback is at least partly counterbalanced by a narrow ing of the distribution curve of the charge signal. In addition, we observe d after proton irradiation at the charge signal spectrum a decrease of the number of small signals. As a result, the efficiency of a CVD diamond track er is less affected by irradiation than the mean charge signal. (C) 2000 El sevier Science B.V. All rights reserved.
