Introduction It was found that the fraction of energy lost per ELM depends on the duration of the ELM compared to the time taken for the energy to be transported along field lines to the divertor plates (see Fig. 1). The energy loss is also affected by collisionality, estimated from the pedestal temperature and density[1,2]. It can be shown that a model of ELMs based on the coupled kink ballooning mode instability (k/b mode), combined with the idea of transport delay in the SOL region, is in agreement with experimental observations.
