As a new approach of neutron generation with the ultra-short pulse duration and high flux, a Laser-Driven Neutron Source (LDNS) has been studied. A demonstration experiment of neutron resonance spectroscopy using a LDNS has been performed using the petawatt laser LFEX at the Institute of Laser Engineering, Osaka University. A CD foil target was used for an high-density plasma generation. Neutrons were produced by the impact of the high energy ions on a boron converter. A high-density polyethylene surrounding the boron converter slowed down neutron energy to epithermal temperature. A single shot neutron resonance experiment was carried out at a neutron beam line of 1.8m. The neutron resonance peak at 4.28 eV of Ta was measured with different temperature.
