Abstract

PURPOSE:To suppress thermal stress by constituting a titled device of supporting seats mounted to one face of a diverter plate, elastic bodies mounted at one end to a vacuum vessel, supporting members to support the supporting seats from the other end, connecting studs and connecting stud rests. CONSTITUTION:The diverter plate 11 adsorbs and removes the impurities generated by sputtering of plasma. A cooling pipe header 10 and a sub-header 10a respectively cool the diverter plate 11. The supporting members 17 mounted to the vacuum vessel 7 support the supporting seats 16 mounted to one face of the diverter plate 11. Springs 18 to play the role of a cushion are installed between the members 17 and the seats 16. Furthermore, connecting bolts 1 connect the seats 16 and the members 17 by means of the springs 18. The connecting studs 20 connect one block of the diverter plate 11 and the connecting studs 21 are mounted to the diverter plate 11. The thermal stresses generated from the plasma are thereby suppressed and the electromagnetic force to rotate the diverter plate 11 generated by eddy current is suppressed.
