| contents | Recent progress of laser science provides laser-driven neutron source (LDNS), which has remarkable features such as the short pulse width. One of the key techniques to be developed for more efficient use of the LDNS is neutron collimation tubes to increase the number of neutrons arriving at a detector in the time-of-flight method. However, when a tube with a thick wall is used as a collimator the neutron collection efficiency at the detector increases but the time resolution becomes wider because of multiple scattering inside of the tube. In the present study, we have developed a collimation tube made of Ni-0, which is optimized for the increased neutron collection efficiency and a reasonable time resolution. This collimator has been demonstrated experimentally using neutron resonance spectroscopy with neutrons provided from LFEX laser. |
