Abstract

The characteristics of the uranium oxide cathodes for a neutron streak tube have been experimentally evaluated, using a conventional streak tube with 2 MCP wafers whose photocathode is changed into an uranium oxide cathode. It has been confirmed from the neutron image on the output phosphor screen that the detection efficiency (fission event/neutron) is roughly between 10-6 and 10-7 and each fission produces a few hundreds electrons emitted into vacuum. The temporal spread of--14ps has been obtained from the streak image of emitted electron cloud per one fission. On the other hand, it has been found from the experiment that in the practical use, the noise generated in the MCPs becomes an obstacle.
