Abstract
A mounting for an object processed at a predetermined temperature in an uahigh vacuum chamber having a stainless steel wall. The mounting has a stainless steel tube welded to the wall and opening through it and has an oxygen-free-high-conductivity copper finger extended from the tube to receive the object. At the junction of the tube and the finger, the tube bears an annular knife edge which engages a flat surface of the finger, and an ultrahigh vacuum seal is established by a collar and bolt coupling which draws the finger against the knife edge. The temperature of the finger and the object are then controlled and measured by cryogenic liquids, electrical heaters, and sensors inserted through the tube into contact with the finger.
Claims3
A mounting for an object which is to have a predetermined temperature while in an ultrahigh vacuum environment, the mounting being inwardly extendable from a wall of an ultrahigh vacuum chamber and comprising:
- a cylindrical tube unitarily constructed of relatively hard material, the tube having one axial end for connection to said wall and having an opposite axial end bearing an annular knife edge unitarily constructed with the tube and circumscribing an opening which extends axially through the tube;
- a generally cylindrical finger unitarily constructed of relatively soft material and having an axial end surface and a receiving portion, the finger selectively being detachable from the tube and being attachable thereto so as to extend coaxially from the tube with the receiving portion extended axially of the finger from the knife edge, the finger closing the opening and being accessible through the opening and the end surface being accessible in a direction radially of the end surface when the finger is detached from the tube;
- coupling means for detachably connecting the finger to the tube and for urging the finger axially toward the tube without relative movement rotationally or radially therebetween to force the knife edge into ultrahigh vacuum sealing relation with said end surface.
