Broadband electronics for CVD-diamond detectors

The application of CVD-diamond detectors for particle detection has created a demand for the development of very fast, low-noise electronics operated at high dc bias voltages. To take advantage of the high charge-carrier mobi lity of the new detector material the signal processing is performed using microwave layout techniques as well as picosecond pulse shapers and GHz-fre quency dividers. The particle detection limits of CVD-diamond detectors pro cessed with low impedance broadband electronics are described. The properti es of the developed electronics are discussed in conjunction with results f rom beam diagnostics operation in the broad energy range of 120 keV/amu up to 2 GeV/amu for GSIs heavy ion accelerators.
