Abstract
The Magnetic Proton Recoil (MPR) neutron spectrometer was installed at the Joint European Torus (JET) in 1996. The present prototype instrument is designed for 14-MeV neutrons. Its capability as a neutron emission spectroscopy (NES) diagnostic was demonstrated during the Deuterium-Tritium Experimental (DTE1) campaign in 1997 and it has since been continuously used during subsequent D-plasma operation. In this paper we describe an upgrade of the spectrometer’s focal plane, recoil-proton detector and radiation shield. The MPRu is intended to make it possible fully to exploit the MPR capabilities in the forward JET experimental programme and to demonstrate the potential role of NES diagnostics in the next step fusion experiments such as planned with ITER.
