Outline of Final Research Achievements

The authors have a great progresses in developing a neutron imaging detector for fast ignition experiment. The tritium-doped target is also necessary for this diagnostics to increase the number of neutron generated in the experiment. We progressed in processing tritium doping to the plastic target. So far, the density of tritium is not enough, thus we cannot generate neuron yield as required for detecting neutron image. The imaging system was completed and tested by using X-ray (alternative to the neutron )generated by electron linear accelerator. The clear x-ray image was observed so that we confirmed neutron imaging system was completed. Neutron imaging collimator is also developed and tested by using X-ray generated in the fast ignition experiment. The clear image was observed thus reconfirmed neutron collimator was well worked.
