Summary:
Multispectral-imaging has proven to be an immensely valuable source of information on the energy and particle dissipation processes at play between a hot fusion plasma and the reactor-wall. In this research, a MANTIS system (developed by DIFFER/EPFL/MIT) was used to study alternative tokamak exhaust solutions for limiting the heat-load on the plasma wall at UKAEA’s MAST-U experiment. The super-X configuration appears to be doing the job of cooling off the exhaust plasma even better than hoped for. Furthermore, MANTIS system’s at SPC’s TCV experiment were used to demonstrate a new method for determining the energy and location of so-called ‘runaway electrons’. This will help to assess the effectiveness of mitigation strategies aimed at limiting the damage that these relativistically fast electrons can do tokamak-reactors.
