Abstract

An evaluation of three different candidate techniques for a 14-MeV High Resolution Neutron Spectrometer for a high power fusion device is presented. The performance is estimated for a modelled neutron emission for ITER plasma scenario 4. As performance indicators we use the estimated time-resolution achieved in measurements of three plasma parameters, namely, the ion temperature, the intensity of neutron emission due to neutral beam - thermal plasma interactions and the intensity of the so-called alpha knock-on neutron tail. It is found that only the MPR technique can deliver results on all three parameters with reasonable time resolution. © 2008 American Institute of Physics.
