Abstract :
Summary form only given. A neutron streak camera was designed for inertial confinement fusion (ICF) fuel ion temperature diagnostic. It is made of a 1 cm thick times 8 cm diam piece of 3% benzophenone quenched Bicron BC-422 plastic scintillator with about a 190 ps FWHM and a streak tube (55 ps time resolution) with large-area photocathode (phi30 mm) showed no slit. The electron beam from the photocathode is focused into a little spot (phi1 mm). Then the spot is scanned directly and multiplied by an internal microchannel plate. This greatly improves the sensitivity of the tube. The neutron streak camera combines the advantages of scintillation detector (with high neutron detection efficiency) and of streak camera (with fast time response). The whole detection system time resolution is 300 ps and can record neutron time of flight signals from ICF implosion target with yields of 107 DT neutron per shot
