| 内容記述 | We report on the membrane diamond detector, which consists of 5 μm-thick p-i-n diodes and a dedicated front-end ASIC, fabricated in a 65-nm CMOS technology. The p-i-n diode has an attractive feature for low γ-ray sensitivities due to its extremely thin drift layer, which is difficult to form by etching of bulk diamond with a Metal?Insulator?Metal structure. The pseudo-vertical p-i-n diode structure was formed on the single crystal diamond {111} substrate by MPCVD and dry-etching process. The readout electronics was designed to meet specifications for real-time neutron monitoring in harsh γ-ray environments. The prototype system was evaluated in charge distribution measurements induced by α-particles from 241 Am. The charge spectra were successfully obtained from multi-channels, each of which has a diameter of 250 μm aligning in a pixel matrix. By combining with neutron converters, e.g. 10 B or 7 Li, we expect the detector system as a good candidate for detecting spontaneous fission neutrons, emitted from submerged fuel debris at the Fukushima Daiichi Nuclear Power Plant in Japan. | |||||||
