Neutron time-of-flight(TOF) can provide important information about the fuel-ion burn temperature in various inertial-confinement-fusion(ICF) target designs.The sensitive neutron detector array is used to increase sensitivity while maintaining good time resolution for low-yield targets.It has been a standard technique to diagnose the average density-radius product ? ρ R?

which is a very important parameter in ICF experiments.The time resolution of the sensitive neutron detector array which will be used in “Shen Guang III” system is expected to be 1 ns

and the one of the electronic system connected with the detectors is 100 ps.Based on the next generation of TDCs from ACAM

TDC-GP2

a VME-plug-in multi-chanel TDC module

with a time-resolution of less than 61 ps

has been designed.
