Development of ion photon emission microscopy at JAEA

We have developed two systems to acquire two-dimensional maps of Single Event Effects (SEEs) by using focused microbeams. While the microbeam has many advantages for SEE testing, the transport and optimization of the microbeam requires much time and effort, especially for high energy heavy ions. Therefore the mapping system with less effort is required, and we are developing the Ion Photon Emission Microscopy (IPEM). Since the spatial resolution is determined by the spot size and the intensity of luminescence, the scintillator is one of the most important parts of IPEM. We propose that the diamond containing Nitrogen Vacancy (NV) centers can be used as a scintillator. For both diamond and YAG:Ce proposed by Sandia National Laboratories, the minimum spot size is a few micrometers. IBIL intensity from diamond is four times higher than that from YAG:Ce. Therefore, we propose that the diamond containing NV centers is a rival candidate of YAG:Ce for IPEM.
