fabrication and welding of quarter wave SRF cavities. The specifications are given
considering the requirements of welding technology development.


The cavities will be made of Niobium. In addition to welding, the supplier should be
able to provide technical support for all the process steps involved in manufacture of the
SRF cavities. Materials like Copper & its alloys, Titanium alloys, Stainless Ste
el, Aluminum
alloys, Niobium & Supper alloys are candidates for welding. The supplier of the Electron
Beam Welding machine should have proven experience of both fabrication and welding of
SRF cavities and should be able to offer a complete solution for man
ufacturing quarter wave
SRF cavities



In addition to the electron beam welding function the proposed system is desirable
for micro
-
machining, surface machining and drilling applications utilizing nano
-
