7. József NÉMETH RST meeting, 17th January 2010, Cadarache, France 7 ITER Goal Oriented training program on PPE ITER CXRS shutter actuator ITER cryostat CXRS port plug 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

8. József NÉMETH RST meeting, 17th January 2010, Cadarache, France 8 ITER Goal Oriented training program on PPE ITER CXRS shutter actuator Description of the appliance pneumatic structure main parts are two bellows inside each other axial shift is controlled by the gas pressure two plates are fixed to the base two internal plates are pushed by the actuator Temperatures Radiation Convection Loads and boundary conditions internal heat generation constrained temperatures temperature dependant convection radiation

9. József NÉMETH RST meeting, 17th January 2010, Cadarache, France 9 ITER Goal Oriented training program on PPE ITER CXRS shutter actuator Results max. temperature 187 [C°] permissible temperature 300 [C°] no critical regions

10. József NÉMETH RST meeting, 17th January 2010, Cadarache, France 10 ITER Goal Oriented training program on PPE ITER CXRS shutter actuator Conclusion additional cooling is not necessary temperature differences are not significant all the wall thicknesses can be adequate Wall thickness 0,3[mm]
