• The ITER Disruption Mitigation System will consist of Shattered Pellet Injectors (SPI) which will be fired upon request into the ITER plasma to mitigate the detrimental consequences of disruptions. Each SPI will include a fast shutter to block the propellant gas after the pellet has passed to minimize the gas amount injected before the pellet, which was found to be critical to maintain disruption mitigation efficiency. An electromechanical test bench (ETB) was designed and built where the electromechanical model of the shutter actuator has been validated. Several material combinations were tested, to find the optimal solution for the fast shutter prototype.
