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.

Positron annihilation spectroscopy using ultra-short pulsed laser Thomson scattered gamma-rays

Laser Thomson/Compton scattering is a unique technique to generate gamma-rays with features such as quasi-monochromatic and tunable energy, highly polarized, low divergence angle, and low background. We have developed GiPALS using an ultra-short pulsed gamma-ray generated at the synchrotron radiation facility UVSOR-III. The gamma-rays are generated via laser Thomson scattering with 90 degree collisions between a 750-MeV electron beam and a Ti:Sa laser. The pulse width of the gamma-rays is calculated to be 5 ps (FWHM). The gamma-ray induced positron annihilation lifetime spectroscopy (GiPALS) is currently available for users. In addition to GiPALS, we develop gamma-ray induced age-momentum correlation (GiAMOC), which measures the lifetime and Doppler broadening of annihilation gamma-rays simultaneously. In this conference, we will present a generation method of the ultra-short pulsed gamma-rays and details of GiPALS and GiAMOC.
