Times Cited Count:0 Percentile:0(Engineering, Electrical & Electronic)In this study, we employed a superconducting detector, current-biased kinetic-inductance detector (CB-KID) for neutron imaging using a pulsed neutron source. We employed the delay-line method, and high spatial resolution imaging with only four reading channels was achieved. We also performed wavelength-resolved neutron imaging by the time-of-flight method. We obtained the neutron transmission images of a Gd-Al alloy sample, inside which single crystals of GdAl were grown, using the delay-line CB-KID. Single crystals were well imaged, in both shapes and distributions, throughout the Al-Gd alloy. We identified Gd nuclei via neutron transmissions that exhibited characteristic suppression above the neutron wavelength of 0.03 nm. In addition, the Gd resonance dip, a dip structure of the transmission caused by the nuclear reaction between an isotope and neutrons, was observed even when the number of events was summed over a limited area of 15 m 12 m. Gd selective imaging was performed using the resonance dip of Gd, and it showed clear Gd distribution even with a limited neutron wavelength range of 1 pm.

Times Cited Count:3 Percentile:25.07(Instruments & Instrumentation)For the J-PARC E40 experiment which aims to measure differential cross-sections of Sp scatterings, a system to detect scattered proton from Sp scatterings is under development. The detection system consists of scintillation fibers with a MPPC readout. A prototype and a readout electronics for MPPC have already been developed. The prototype consisting of a scintillation fiber tracker and a BGO calorimeter was tested with a proton beam of 80 MeV. Energy resolutions of the tracker of 22.0% (s) and the calorimeter of 1.0% (s) were obtained for 1 MeV and 70 MeV energy deposit, respectively. The prototype readout electronics has an ASIC for multichannel operation, EASIROC, and a Silicon TCP (SiTCP) interface to communicate with a DAQ system. Its data transfer rate measured was 14 kHz. Required performances for the prototype system have been achieved except for the energy resolution of the prototype fiber tracker.

We developed All-Sky Gamma-Ray Compton Camera based on Scintillators. We measured the residual dose rate in F1 by using this detector. Additionally, we measured the residual dose rate at beam line in J-PARC 3 GeV RCS, where has a high dose-rate from 0.01 to 1 mSv/h caused by beam loss during beam operation. We performed the experiment that we can use the detector in the RCS. As the result, we evaluated to obtain -ray imaging of dose rate, which is consistency the measured one by using other detectors. In our presentation, we will report these results.
