| 内容記述 | We generated high-energy neutrons by (d, n) and (p, n) reactions on a Be target with protons and deuterons that were accelerated up to 30 and 10 MeV/u, respectively, by laser-plasma interactions. Thermal neutrons were subsequently generated through deceleration by a small moderator with conjunction on the Be target. Here we report the measurements on the thermal neutron fluence using the activation method with/without Cd filters. The unstable isotopes of 198Au, 56Mn, 60Co, and 181Hf were produced through (n, γ) reactions by a single laser shot. The nuclear reaction rates were evaluated by measurring the γ-rays emitted from these unstable isotopes. The thermal neutron fluences from the four nuclides are consistent within their experimental uncertainties. The fluence is evaluated to be (2.2±0.4)×105 neutrons/cm2 at the distance of approximately 9- mm at 90◦ against the laser axis. The present result shows that the method to generate thermal neutrons from a compact neutron source with a diamater of 44 mm and length of 46 mm is expected to be a useful tool for various nuclear experiments. |
