Neutron resonance transmission analysis (NRTA) is a method for non-destructive measurement of nuclear material by using a time-of-flight (TOF) technique with a pulsed neutron source. For NRTA system to carry out the short-distance TOF measurements with high resolutions, a short-pulsed neutron source is required. Laser-driven neutron sources (LDNSs) is very suitable as such a neutron source because of its short pulse width. Moreover, the compactness of the laser system is also expected due to the remarkable development of laser technology in recent years. In the present study, we have developed a technology for applying LDNS to the NRTA system and conducted the demonstration experiment using the LFEX laser at Osaka University to investigate the feasibility of the system. In this experiment, we successfully observed the neutron resonance peaks of indium and silver samples.

Recent development of neutron detectors for pulsed compact neutron sources

Compact neutron sources have been used as various diagnostics such as a neutron diffraction, neutron resonant analysis, and neutron radiography. The developments of the neutron detectors are essential for all of these applications, while the techniques are strongly dependent on the neutron energy and the aim of the measurement. This paper reviews neutron detection techniques pertinent to promote compact neutron source uses. Along with general neutron detection systems with conventional counters for slow neutrons, we have highlighted detectors for high energy neutrons with high time resolution and high sensitivity which could be applied in a laser-driven compact neutron source.

X-ray line spectra ranging from 17 to 77 keV were quantitatively measured with a Laue spectrometer, composed of a cylindrically curved crystal and a detector. Either a visible CCD detector coupled with a CsI phosphor screen or an imaging plate can be chosen, depending on the signal intensities and exposure times. The absolute sensitivity of the spectrometer system was calibrated using pre-characterized laser-produced X-ray sources and radioisotopes. The integrated reflectivity for the crystal is in good agreement with predictions by an open code for X-ray diffraction. The energy transfer efficiency from incident laser beams to hot electrons, as the energy transfer agency for specific X-ray line emissions, is derived as a consequence of this work.

High-intensity laser and thin-foil interactions produce high-energy particles and hard X-ray. A proton beam driven by a high-intensity laser has received attention as a ion source for medical and other applications. We have performed high energy laser-matter interaction experiments using a thin-foil target irradiated by LFEX laser at Osaka University. The three beams were focused at a thin-foil target. The maximum proton energy of $$sim$$40 MeV energy were observed at the total laser energy of $$sim$$700 J. The preliminary experiment for plasma mirror are started.

Some nondestructive assay (NDA) methods for validation of highly radioactive nuclear material have been developed under the subsidiary for nuclear security promotion of MEXT. Nuclear Resonance Transmission Analysis (NRTA) is able to measure the density of each isotope of fissile and quite useful for analysis of solid samples like fuel debris. However, it is not easy to install due to a large Time-of-Flight (TOF) system which is required for the precise measurement. So, we have proposed a NRTA combined with Laser Driven Neutron Source (LDNS). TOF system would be shortened less than 5 m because of extremely short pulse width of LDNS. A conceptual design of LDNS-NRTA will be presented.

Under the subsidiary for "promotion of strengthening nuclear security or the like" of MEXT, development of nuclear non-proliferation technologies are in progress. One of the research programs is development of laser driven neutron source for neutron resonance transmission analysis (NRTA).

We have been developing Nuclear Resonance Transmission Analysis (NRTA) using Laser Driven Neutron Source (LDNS) as a part of nuclear non-proliferation technology development supported by the MEXT (Ministry of Education, Culture, Sports, Science and Technology) subsidy program "promotion of strengthening nuclear security and the like". An LDNS, which can generate short pulsed neutrons from a small volume, is considered to potentially have large benefits for the NRTA. In order to demonstrate the NRTA using the LDNS, the transmission measurements have been carried out by the TOF method using the LFEX laser at Osaka University. The results are reported here.
