Outline of Final Research Achievements

A neutron energy distribution is expected to provide information of a laser-driven proton energy during neutron generation with the laser-driven proton and neutron converter. In order to comparison, the neutrons were measured during laser-driven proton generation without neutron-converter. Laser protons were produced repeatedly and measured a neutron with a bubble detector which is sensitive only towards neutrons. The dose of the neutron was approximately 0.1Sv/shot. A time-of-flight-type neutron detector integrated with a the scintillator was used to detect the neutrons to determine the neutron energy. Furthermore, a neutron spectrum at the time of the neutron conversion was calculated. I will clarify the effectiveness as the proton energy measurement method.
