12GeV Project CD-4 Leigh Harwood Associate Project Manager Accelerator Systems

6 GeV CEBAF Two 0.6 GeV linacs CHL-2 12 Upgrade magnets and power supplies 1.1 New cryomodules get new rf zones Add arc Add 5 cryomodules Add beamline HD refrigerator

CD4: Key Performance Parameters CD-4 is phased –CD-4A: Accelerator and Conventional Facilities –CD-4B: Experimental systems Complete

Schedule 1.3.1, 1.3.3, 1.3.4, and are complete in FY and extend into FY14 but will not hinder commissioning CD-4A Proposed CD-4B Accelerator (CD-4A KPP) Hall A (Not a CD-4 KPP) Hall D (CD-4B KPP) Hall B & Hall C (CD-4B KPP)

Schedule (cont’d) CD4A Accelerator Hall D Not needed for Hall D beam commissioning or CD4 Not needed for Hall A beam commissioning 6-months schedule float to CD-4A Hall A

CD-4A Float 6+ months 12 months CD-4A

Summary On track to complete CD-4A KPP’s early –Accelerator and beamline installation 6+ months float –Accelerator beam commissioning12 months float
