Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for fabricating accelerator cavities comprising: forming two half cavity pieces of an RF resonating cavity; and joining said two half cavity pieces of said RF resonating cavity with a single longitudinal seam, such that the longitudinal seam intersects a cavity opening at a perpendicular angle, thereby forming an RF resonating cavity, wherein during operation of the RF resonating cavity an induced RF current does not cross the longitudinal seam. 2. The method of claim 1 wherein said two half cavity pieces of said RF resonating cavity comprise at least one of: aluminum; copper; tin; and copper alloys. 3. The method of claim 1 further comprising: spraying a coating on said two half cavity pieces of said RF resonating cavity. 4. The method of claim 3 wherein said coating comprises a superconductor. 5. The method of claim 4 wherein said superconductor comprises one of: niobium; MgB2; and Nb3Sn. 6. The method of claim 1 further comprising heat treating said RF resonating cavity after joining said two half cavity pieces of said RF resonating cavity with a longitudinal seam thereby forming an RF resonating cavity. 7. The method of claim 6 wherein heat treating said RF resonating cavity further comprises: heating said RF resonating cavity to a temperature ranging from 600° C. to 1100° C. 8. The method of claim 1 wherein joining said two half cavity pieces of said RF resonating cavity with a single longitudinal seam thereby forming an RF resonating cavity further comprises: applying a brazing agent to the two half cavity pieces where they will be joined; and brazing the two half cavity pieces together forming the single longitudinal seam. 9. A method for fabricating accelerator cavities comprising: forming two half cavity pieces of an RF resonating cavity; applying a superconducting coating to at least one surface of said two half cavity pieces of said RF resonating cavity via one of vacuum plasma spray, physical vapor deposition, sputtering, ion-beam deposition, evaporation, and laser ablation; joining said two half cavity pieces of said RF resonating cavity with a longitudinal seal such that the longitudinal seal intersects a cavity opening at a perpendicular angle, thereby forming an RF resonating cavity, wherein during operation of the RF resonating cavity an induced RF current does not cross the longitudinal seam; and heat treating said RF resonating cavity wherein heat treating said RF resonating cavity further comprises heating said RF resonating cavity to a temperature ranging from 600° C. to 1100° C. 10. The method of claim 9 wherein said two half cavity pieces of said RF resonating cavity comprise at least one of: aluminum; copper; tin; and copper alloys. 11. The method of claim 9 wherein said superconductor comprises one of: niobium; MgB2; and Nb3Sn.
