“…Potassium cryolite materials exhibit high light output (>20000 photons/MeV), good energy resolution ( E = 662 KeV, < 5%), and excellent n/ discrimination capability [361]. However, they have some limitations in the detection of fast neutrons [362]. A. Gueorguiev and others have developed a new technology that combines inorganic scintillator (CLYC) with an organic scintillator matrix (methyl methacrylate, PMMA) to achieve simultaneous detection of fast neutrons, thermal neutrons, and -rays.…”

Abstract“A Craftsman Must Sharpen His Tools to Do His Job,” said Confucius. Nuclear detection and readout techniques are the foundation of particle physics, nuclear physics, and particle astrophysics to reveal the nature of the universe. Also, they are being increasingly used in other disciplines like nuclear power generation, life sciences, environmental sciences, medical sciences, etc. The article reviews the short history, recent development, and trend of nuclear detection and readout techniques, covering Semiconductor Detector, Gaseous Detector, Scintillation Detector, Cherenkov Detector, Transition Radiation Detector, and Readout Techniques. By explaining the principle and using examples, we hope to help the interested reader underst and this research field and bring exciting information to the community.

“…The 6 Li:ZnS(Ag) screen is a practical choice for us to make a large area detector in terms of availability and the cost. The screens are purchased from SCINTACOR, UK that have mass ratios of ZnS to 6 LiF as 2 to 1. Although a large afterglow of the 6 Li:ZnS(Ag) limits the count rate capability less than about 5000 cps, it is acceptable for most diffraction measurements in the BL19 [6].…”

“…In this experiment we tried to find out the practical solution from the commercial products. The available 6 Li:ZnS(Ag) screens type ND from the SINTACOR, UK have the thicknesses of 0.3 and 0.5 mm with a 6 Li content of 1.5 × 10 21 1/cm 3 . Figure 2(b) shows a relative neutron count to a reference detector.…”

Large area, two-dimensional scintillation neutron detectors were developed for TAKUMI engineering neutron diffractometer at the Materials and Life Science Experimental Facility, Japan Proton Accelerator Research Complex. The detector was made based on a scintillator/wavelength shifting fiber technology. The detectors have neutron-sensitive area of 320 × 320 mm with a pixel size of 5 × 5 mm, which is about 1.56-fold larger than the original SENJU detector. The thicknesses of the 6 Li:ZnS(Ag) scintillator screens were selected to 0.3 mm for both the front and rear scintillator screens. The detectors which are equipped with new discriminator electronics decreased a required PMT voltage to 86% of the maximum rating of the multi anode PMT (type H8804, Hamamatsu, JAPAN). The produced three detectors exhibit detection efficiencies of 40~48% for 2-Å neutron. The detectors have count uniformities to 6% (1). These detectors have been installed to the TAKUMI diffractometer at the scattering angle 2 of 157 degree and in service since 2017.

“…The event position is determined by using a direct encoding technique with multi-anode PMT's. Newly developed sintered ceramic scintillator material, ZnS/ 10 B 2 O 3 , improved detecting efficiency, gamma sensitivity and afterglow at the same time [18] We are now implemented those detectors in iBIX (1.2 mm resolution) [19], SENJU (4 mm resolution) [20] and SHARAKU (4 mm resolution) [21] as shown in Fig. 8.…”

The facility has resumed since 17th February 2014 after reformation of operation safety system required from the new regulation because of the accident in the Hadron Facility in May 2013. During eight-month shutdown period various hardware components have been improved; such as installation of additional RFQs in Linac to increase its energy to achieve higher power, repairing and replacement on the mercury (Hg) cooling loops of the neutron target, improvement on the cryogenic system for stable operation, etc. In order to mitigate the pitting damage on the Hg-target container we have been injecting helium micro bubbles in the target. The laser Doppler vibrometory showed us that vibration on the proton bombardment has been drastically reduced by the injection. Twenty one instruments have been already installed. Sixteen instruments are operated for user program and four instruments are under either commissioning or construction. Now the experimental hall is almost full with instruments, leaving only 2 ports available for the future use. Operational time for user program in JFY2014 was about 170 days, and we received more than 700 general experimental proposals from users. World-class scientific outputs have been being created in various scientific fields, ranging from Li-battery science to bio-molecular science. Since J-PARC is internationally open for users, we have got experimental proposals from abroad, which are more than 15% of the whole proposals. More than 20% of proposals have come from industries and a half of them are proprietary use. This fact has revealed a new horizon has come in the neutron scattering science in the 21 century.
