Neutron time of flight energy spectrometer for ICF ion temperature diagnostic

摘要

A current-mode neutron time-of-flight (nTOF) energy spectrometer for inertial confinement fusion (ICF) ion temperature measurements has been designed which will reduce measuring error shallow cup-shaped ST1422 fast plastic scintillator with a thickness of 3 mm and full effective volume of 104 cm~3, a microchannel plate photomultiplier tube (MCP-PMT), a piece of coaxial calbe (SUJ-50-7) with a length of 20 m, and a transient oscilloscope with a bandwidth of 7 GHz.
