Longitudinally joined superconducting resonating cavities
A system and method for fabricating accelerator cavities comprises forming at least two half cavities and joining the half cavities with a longitudinal seal. The half cavities can comprise at least one of aluminum, copper, tin, and copper alloys. The half cavities can be coated with a superconductor or combination of materials configured to form a superconductor coating.
1. A system comprising:
two cavity pieces of an RF resonating cavity; and
a longitudinal seam joining said two cavity pieces of said RF resonating cavity, wherein the longitudinal seam is configured such that the longitudinal seam intersects a cavity opening at a perpendicular angle, thereby forming the RF resonating cavity, wherein during operation of the RF resonating cavity, an RF current does not cross the longitudinal seam.
2. The system of claim 1 wherein said at least two pieces of said RF resonating cavity comprise at least one of:
aluminum;
copper;
tin; and
copper alloys.
3. The system of claim 1 further comprising:
a coating applied to said at least two pieces of said RF resonating cavity.
4. The system of claim 3 wherein said coating comprises a superconductor.
5. The system of claim 4 wherein said superconductor comprises one of:
niobium;
MgB 2 ; and
Nb 3 Sn.
6. The system of claim 1 further comprising:
a heat treatment cycle applied to said RF resonating cavity.
7. The system of claim 6 wherein heat treatment cycle further comprises:
heating said RF resonating cavity to a temperature ranging from 600 ° C. to 1100° C.
8. The system of claim 7 further comprising:
a pattern formed in at least one surface of said RF resonating cavity applied via one of patterning and lithographic processes configured to tailor an electric field configuration therein.
