Diamond as a Particle Detector

This report surveys the detector properties of CVD-diamond samples and CVD-diamond strip detectors with respect to charge collection, spatial resolution and radiation damage. The collected charge on diamond samples and strip detectors to date is at detectors with 4000 electrons. Diamond strip detectors with 50 $\mu \rm{m}$ readout pitch have been built and putinto beam tests. Using a low noise readout with 2 $\mu \rm{s}$ shaping time, a resolution of 14 $\mu \rm{m}$ has been demonstrated. The diamond samples show no degration of charge collection after irradiation with electrons, photons and pions and small decrease after neutron irradiation.
