ERL Status & Schedule
• Although important to C-AD, ERL must compete for resources with machine operations –
– Sharing resources limits the work that can be performed… During shutdown periods Operations maintenance days Anytime ERL work is in conflict with operations efforts
– Best efforts are being made by all ERL-involved groups but schedule slip can and does occur.

• The critical path remains the electron gun cavity cryomodule– Steps to complete the cryomodule include:
Cavity processing Hermetic Cavity String assembly String installation into e-Gun cryomodule
– G-5 (e-Gun to 5 cell Cavity) next major milestone– Followed by the full ERL complete

• Major Milestones G-5 Testing
• Requires e-Gun installed in Cryomodule All major cryomodule components ordered e-Gun cryogenics lines routing design in process
• Requires G-5 magnets, instrumentation and vacuum chambers
• All magnets and stands in-house• Installation as time permits
• Remainder of G-5 vacuum chambers due 04/28/10• Beam instrumentation for G-5 & ERL due 08/26/10
• Removal of G-5 “straight” line & install “zig-zag” line• Additional testing with this configuration
