Outline of Final Research Achievements

As an exit window as well as a transmission position sensitive detector for high energy ions transmitted to atmosphere, a novel membrane device made of single crystal diamond has been developed. A test device was made and the ion-beam-induced charge (IBIC) or the time measured response (QTS) made a comprehensive evaluation. Watching the first IBIC measurement of ion incident position-dependent output signal. In addition and comparison between experimental and calculated deterioration characteristics associated with the increase in signal strength dose, proposed a new degradation parameter. The electrical activity of single crystal diamond semiconductor investigated by QTS. In addition confirmed new phenomenon due to the avalanche effect induced by ion beam generation charge amplifier.
