Development of time-of-flight neutron detector with fast-decay and low-afterglow scintillator for fast ignition experiment

摘要

A fast-decay and low-afterglow liquid scintillator was developed for the fast ignition experiment at the Institute of Laser Engineering (ILE). The liquid scintillator was coupled to a gated photomultiplier (PMT), and the gating performance under high-intensity γ-rays was experimentally checked. In 2010, a detector with a high detection efficiency of 10?4 was developed and installed in this experiment. The neutron yield in the fast heating experiment was successfully measured using this detector.
