Paper Abstract

A geometry-compensated shallow cup-shaped ST1422 plastic scintillator neutron time-of-flight (nTOM) detector has been designed and used on SG-II laser facility to diagnostic inertial confinement fusion (ICF) ion temperature in direct- drive implosions with yields of 108-109 DT neutrons. The measurement system consists of a shallow cup-shaped ST1422 fast plastic scintillator with a thickness of 5mm and full effective volume of 170cm3 placed at a distance of 5.25m from the target, a microchannel plate photomultiplier tube, a piece of coaxial cable with a length of 10m, and a transient oscilloscope with a bandwidth of 4.5GHz. The rise- time and FWHM of the temporal response function are 390ps and 1.47ns, respectively. Measured result for several shots are presented.
