Develop treatment for SPL sc cavities at CERN (In particular for β= 0.65) Develop treatment for SPL sc cavities at CERN (In particular for β= 0.65) (*) The HPWR has not been operated for > 2 years. Diagnostics, controls, need to be replaced. All system needs cleaning/revamping. A proposal was made for last year (“SCRF facility”), we re-iterate this request for 2010
Contribute to cryomodule design Cryogenics/vacuum sectorisation Coupler issues: surface treatments, outgassing
SC linacs maintain beam quality for energy variable machines SC linacs maintain beam quality for energy variable machines The maximum effective voltage can be applied to lighter masses so to have a higher final energy. Quarter waver cavities already well-known in several labs Nb/Cu technology chosen over bulk-Nb for mechanical stability (reduction of microphonics and sensitivity to He bath pressure), no magnetic shielding (simpler cryostat), lower cost
Lead the work to transform the RF design into a real accelerating cavity that satisfies design specifications. - Coordination of mechanical design: for the cavity, the coating system, the chemistry facilities and all related tooling. To set-up SC samples testing
- Coordination of mechanical fabrication
- Optimisation of surface treatment and coating
- Definition of vacuum overall layout for cryomodule
Cavity prototype: coating development, surface treatment optimization, achieve nominal specifications by end 2009 - Giulia Lanza, Antonio Mongelluzzo, Jean Cave, Leonel Ferreira, Serge Forel.
HIE-linac general vacuum layout: define requirements and specifications, hardware definition, diagnostics. HIE-ISOLDE front end: optimization of vacuum issues (hardware location, maintenance) in a highly radioactive environment
