Notes:
Detection efficiency and secondary electron yield of the uranium-oxide cathode for a neutron streak camera were measured and found to be 2.3×10−7–1.6×10−6 events/neutron/μm and 60–150/fission, respectively. These measurements were performed for 14-MeV neutrons from a D-T neutron source (OKTAVIAN) by using neutron-imaging techniques. By defocusing an image due to a single fission event, each electron from the cathode was clearly distinguished, and the number of electrons could be counted. From the neutron images in the streak-mode operation, time dispersions due to the electron transit-time spread fell in the range of estimated values.
