abstract = {The research on plasma facing components in view of plasma
wall interactions is advancing towards a new level with the
availability of long pulse plasma machines. With Wendelstein
7-X (W7-X) the first stellarator provides steady-state
discharges with up to 30 min in the next operation phase
(OP2). To support the investigation of PWI processes with
fast sample and component exchange, a divertor manipulator
and accompanying observation system with laser injection is
in development.The introduction of probe heads into the W7-X
plasma proceeds roughly along the developed use cases for
diagnostic analysis, sample testing probe heads and finally
high heat flux capable probe head designs. The thermal
performance and limits of sample holding designs is
simulated for an actively cooled probe head design. For
testing and qualification of thermal and diagnostic
capabilities of probe heads an UHV exchange chamber and
linear drive system is developed for plasma exposure at the
linear plasma generator PSI-2. The observation system design
is modified to include a coaxial laser injection system.},
