| Research Abstract |
The aim of the present study is to explore the origin of the neutron-deficient stable p-nuclei through the reaction measurements using radioactive isotope beams. For this experiment, strip-silicon detectors of a large sensitive area (~90mmx90mm) and their readout circuits are needed. In particular, the readout circuit require the large dynamic range of about 5000 and capability of high density signal processing of several thousand channels, and must be newly developed. In this study, the silicon strip detectors and readout circuits are newly designed, and succeeded to develop the circuits that satisfy the requirements.
