Description
As nuclear and particle physics facilities move to higher intensities, the
detectors used there must be more radiation tolerant. Diamond is in use at
many facilities due to its inherent radiation tolerance and ease of use. We
will present radiation tolerance measurements of the highest quality
poly-crystalline Chemical Vapor Deposition (pCVD) diamond material for
irradiations from a range of proton energies, pions and neutrons up to a
fluence of 2 x 10^16 particles/cm^2. We have measured the damage constants
as a function of energy and particle species and compare with theoretical
models. We also present measurements of the rate dependence of pulse height
for non-irradiated and irradiated pCVD diamond pad and pixel detectors,
including detectors tested over a range of particle fluxes up to 20 MHz/cm2
with both pad and pixel readout electronics. Our results indicate the pulse
height of unirradiated and neutron irradiated pCVD diamond detectors is not
dependent on the particle flux.
