Abstract
A new scheme for suppression of runaway electrons in ITER disruptions is proposed. It is based on maintaining the magnetic perturbations during the entire current quench phase by exciting kink modes using repetitive high pressure gas injection to the plasma edge. The total amount of gas injected is expected to be compatible with the ITER pumping system.
