Multi-Purpose Manipulator

The Multi-Purpose Manipulator (MPM) is a versatile carrier system for probe heads mounted at the outer mid-plane of W7-X (port AEK40). It consists of two stacked linear drives: The first drive carries the probes from outside the cryostat to the plasma vessel wall. From that position, the second linear drive can perform fast plunges with an acceleration of up to 30m/s² and a distance of up to 350mm into the plasma. The island chain and the last closed flux surface can be crossed in all magnetic configurations.
