CVD diamond is a remarkable material for the fabrication of particle and ph
oton radiation detectors. The improvement of the material electronic proper
ties has been under intensive investigations and led to the development of
a few applications that are addressing specific industrial needs. In partic
ular, we have used diamond layers for industrial applications where it exhi
bits attractive characteristics as compared with other materials : e.g., ra
diation and corrosion hardness for alpha counters or high gammameters at hi
gh fluxes; high transparency to low energy X-rays for synchrotron beam line
monitoring devices,... etc.
