Abstract

In this work we report the results of a first series of neutron measurements carried out at JET during the last experimental campaigns (C17-C19) using super-heated fluid detectors (SHFD’s). The SHFD’s were located in the neutron beam propagating along a collimated vertical line-of-sight, above the TOFOR neutron time-of-flight spectrometer (KM11 diagnostics). The radial distribution of the neutron fluence in the neutron beam was obtained with less than one cm spatial resolution. The neutron spectrum in the neutron beam was obtained over a broad energy range (six energy bins, from 10 keV to 20 MeV)..
