| Outline of Final Research Achievements |
We aimed to explore the possibility of neutron backlight measurement with final density target of inertial fusion implosion core surface density measurement. A neutron source is a γn neutron generated when a target is irradiated with a high intensity laser. At the time of the start of the study, the mechanism of occurrence was unknown, and in this research, emphasis was focused on elucidation of the mechanism of its occurrence and measurement of neutron measurement instruments, high-speed electrons that drive generation, and elucidation of behaviors. Through research, we have found that neutrons are γn neutrons, that neutron generation greatly changes due to high-speed electron and target interaction, elucidation of behavior through computer simulation, development of measuring instruments capable of discriminating γ-rays and neutrons, And experimentally clarified the thickness necessary for the core surface density.
