Shutter
EFDA task under the direction of FZJ
Main aims: - temperature field of shutter actuator - necessity of additional cooling - optimal wall thickness of bellows
Description of the task

ITER CXRS shutter actuator
Conclusion
additional cooling is not necessarytemperature differences are not significantall the wall thicknesses can be adequate
Wall thickness 0,3[mm]
