METHOD OF ADAPTER MANUFACTURING TO CONNECT RESONATOR WITH CASING OF COLLIDER CRIOMODULE Russian patent published in 2015 - IPC H05H7/00 

FIELD: machine building.

SUBSTANCE: first of all flange is manufactured. Disc (2) is cut out of stainless steel, then disc is clad from both sides by Nb or Ti plates (3) due to joint (5) made by explosive welding. The fabricated tri-metal disc is straightened and turned to size equal to outside diameter of the collider casing. Then hole with diameter equal to outside diameter of NB nozzle (1) is cut out, the nozzle is inserted in the hole of the fabricated flange and welded (joint 4) at both sides of the hole to the Nb or Ti plate edges by electron-beam welding. For complete elimination of intermetallic compounds creation the explosive welding of the steel disc with Nb or Ti plates is performed via the Ni interlayer.

EFFECT: assurance of required accuracy of adapter dimensions, exclusion of intermetallic compounds creation in the welded joint, exclusion of liquid helium leaks in cavity of the Nb resonator, decreasing of material consumption during nozzle manufacturing.
