The TOFOR neutron spectrometer and its first use at JET

A time-of-flight neutron spectrometer (TOFOR) has been developed to measure the 2.45  MeV  d+d→ 3 He +n neutron emission from D plasmas. The TOFOR design features the capability to operate at high rates in the 100  kHz range, data collection with fast time digitizing and storing, and monitoring of t...

Description
Summary:A time-of-flight neutron spectrometer (TOFOR) has been developed to measure the 2.45  MeV  d+d→ 3 He +n neutron emission from D plasmas. The TOFOR design features the capability to operate at high rates in the 100  kHz range, data collection with fast time digitizing and storing, and monitoring of the signals from the scintillation detectors used. This article describes the principles of the instrument and its installation at JET and presents preliminary data to illustrate the TOFOR performance as a neutron emission spectroscopy diagnostic.
