Modernisation of the ILC Cryomodule Using High-tech Tchnology – Explosion Welding | |
|
||
| The world first samples of Ti and Nb tubes joint with stainless steel ones by an explosion welding by the JINR-VNIIEF-FNAL-INFN cooperation were manufactured in the frame of ILC R&D program. An applying methods of relaxation of residual tensions (after explosion and electron beam welding), macro-and microanalyses of welding seam and cryogenic tests of the samples produced manifest the achievement of high mechanic strength (~250 MPa/share) of welding seam, solidity and leak absence on 10-10 l*atm/sec level at 1.8 K. The explosion welding technology and methods introducing to industrial manufacturing of the 4-th generation of cryomodule of TESLA TYPE DESIGN can exclude the Ti – communications as cover of the vessel. The Agreement between JINR and E.Paton IEW (Kiev, Ukraine) was achieved for manufacturing Nb+SS transition samples using new technology and new design of Nb+Ti+SS junction. We suppose this samples should be more technological, simpler in manufacturing and cheaper. | ||
