f Cavity Processing Program Cavity Processing Program Fermilab • There are two missions to serve: – Prepare for Project X cavity production—i.e. increase lab-based capacity and industrialize as much processing as is practical to ensure high yield. – R&D and process improvement reach ILC goals • These missions intersect across facilities, schedules and people. • Both missions overlap significantly. Both missions overlap significantly – High yield throughput – Gradient improvement – Process simplification – Process modification – Alternative technologies Alternative technologies May 18-19, May 18-19, 2009 2009 DO DOE SRF Review SRF Review 3
