Abstract
Steady-state H-modes in type III ELM regime on TdeV with electron
cyclotron and lower hybrid heating are investigated with respect to lower
hybrid wave coupling, threshold power, helium pumping and separation between
separatrix and surrounding structures. Energy confinement is found to improve
as the distance between separatrix and divertor baffle is reduced. With
off-axis EC heating, reduced particle transport is observed inside the
deposition zone, but no energy transport barrier is obtained. New measurements
on compact toroid fuelling are reported which indicate that further
optimization of the injector is required.
