Abstract

The progress on the neutron time of flight (nTOF) detection system for Fast Ignition (FI) related experiment was presented. The novel nTOF detector consists with custom-developed liquid scintillator and gated PMT was implemented. The origin of the harsh backgrounds which had been observed in previous experiment was identified by Monte Carlo simulation. The neutron yield around 106 in the 1 kJ-heating experiment which is 10 times lower than previous lower limit was clearly diagnosed.
