| Outline of Final Research Achievements |
The purpose of this study is to develop a small detection apparatus for proton computed tomography using silicon strip detectors and a calorimeter. We have improved the electronic circuits and FPGA program for the readout of SSD signals in order to enhance the speed of the system. The YAP (YAlO3(Ce) perovskite) , which is one of the fast inorganic scintillators, was also tested. It was confirmed that the energy resolution of YAP has enough performance at low-beam intensities and the SSD worked up to a beam intensity of 400 kHz. It was found there were more noises or pulse pileups than expected. They were caused by high-intensity beams.
