Impact of nitrogen seeding on L–H transitions and their role for detachment in ASDEX Upgrade
The required heating power, $P_{\mathrm{LH}}$ , to access the high confinement regime (H-mode) in nitrogen seeded deuterium plasmas is investigated at the ASDEX Upgrade tokamak. It is shown that a stepwise increase of the nitrogen seeding level increases

Balancing physics priors and data for disruption prediction in future tokamaks
Disruption remains a major barrier to the safe, sustained operation of tokamaks. Although current understanding of disruption physics is broadly valid across existing tokamaks, it cannot provide accurate disruption prediction rules.

Stellarators with enhanced tritium confinement and edge radiation control
A stellarator design is described with the purpose of achieving three goals: (1) enhance the confinement time of tritium. (2) Have a sufficient density of high- Z impurities to radiate the thermal power escaping from the core while having an extremely ...

SPECTRA ANALYSIS OF RUNAWAY ELECTRON SYNCHROTRON RADIATION FOR THE RECENT EAST RUNAWAY EXPERIMENT
The energy of disruption generated runaway electrons can reach as high as tens of megaelectronvolt and they can cause a serious damage of plasma-facing-component surfaces in large tokamaks like International Thermonuclear Experimental Reactor (ITER). The
