First applications of CVD-diamond detectors in heavy-ion experiments

Test measurements with Am-241-alpha-particles, C-12, Ne-20, Ni-58, Pb-208 a nd U-238 projectiles are performed. It is shown that the most important cha racteristics of heavy-ion diamond detectors are described by the shaping pa rameters of the detectors single pulse. Distributions of rise and decay tim es of the signals as well as of the associated charge amplitudes are discus sed. An intrinsic time resolution well below 100 ps and a single-pulse widt h of 1 ns are achieved. First applications of CVD-diamond detectors in heav y-ion accelerator beam diagnostics, in heavy-ion experiments and a promisin g first test in the GSI's heavy-ion tumor-therapy project are presented.
