First Applications of CVD-Diamond Detectors in Heavy-ion Experiments

Test measurements with 241Am-α-particles, 12C, 20Ne, 58Ni, 208Pb and 238U projectiles are performed. It is shown that the most important charactristics of heavy-ion diamond detectors are described by the shaping parameters of the detectors single pulse. Distributions of rise and decay times of the signals as well as of the associated charge amplitudes are discussed. An intrinsic time resolution well below 100 ps and a single-pulse width of 1 ns are achieved. First applications of CVD-diamond detectors in heavy-ion accelerator beam diagnostics, in heavy-ion experiments and a promising first test in the GSI's heavy-ion tumor-therapy project are presented.
