"Neutron rate estimates in MAST based on gyro-orbit modelling of fast ions"

A. Sperduti M. Cecconello S. Conroy A. Snicker

A discrepancy between predicted and measured neutron rates on MAST using TRANSP/NUBEAM was observed. Further causes of this discrepancy are here studied by means of TRANSP/NUBEAM and ASCOT/BBNBI simulations. Gyro-Orbit simulations resulted in an approximately 20 % reduction of the fast ion density compare to the Guiding Center with TRANSP/NUBEAM…

"The Neutron Camera Upgrade for MAST Upgrade"

Marco Cecconello A. Sperduti I. Fitzgerald S. Conroy S. J. Holm M. Weiszflog

A Neutron Camera (NC) was used on the Mega Ampere Spherical Tokamak (MAST) to measure the DD neutron emissivity along four collimated lines of sight, two on-axis and two off-axis, all viewing the plasma in tangential direction. The encouraging results obtained suggested that an upgraded NC for MAST-U would provide fundamental information for the st…
