Radiation asymmetries during the thermal quench of massive gas injection disruptions in JET
Original language description
Radiation asymmetries during disruption mitigation by massive gas injection (MGI) can result in substantial first wall heat loads in ITER and have, therefore, to be minimised. Thispaper gives a first analysis of the relation between the magnetohydrodynamic instabilities governing the thermal quench (TQ) and the toroidal distribution of the radiated power duringMGI experiments at JET. It is found that the radiation asymmetry is closely linked to the toroidal phase of the n = 1 mode. The mode phase, on the other hand, is influenced by theinjection itself, with the O-point of the mode being displaced towards the injection location. The development of a m = 1 component during the TQ has been identified from temperatureand soft x-ray measurements.
