CVD-diamond-based position-sensitive detector test with electron beam from a Rhodotron/sup TM/ accelerator

A position-sensitive detector using insulating-type CVD diamond as its substrate material has been developed at the Advanced Photon Source (APS), Argonne National Laboratory, and was tested with a 5 MeV electron beam from a CW Rhodotron/sup TM/ accelerator at the STERIS Corporation. The preliminary test result shows that the free-standing insulating-type CVD-diamond acts as a solid-state ion chamber under the 5 MeV electron beam. Potential applications of the CVD-diamond-based position-sensitive detector, e.g., as a high-dose-rate beam profiler for industrial electron accelerators and radiation technologies are discussed in this paper.
