Upgrading the CEBAF Accelerator to 12 GeV
Jefferson Lab is preparing to upgrade its 6 GeV Continuous Electron Beam Accelerator Facility (CEBAF) to 12 GeV. The doubled energy will significantly extend research reach of the three existing experimental Halls A, B and C, and the upgrade will add scientific capability, with a newly constructed hall, Hall D. Areas of special initial interest are reactions at high xBjorken, GPD's and exotic hybrid mesons. The present linacs will have their acceleration roughly doubled through the addition of 10 new cryomodules which will perform at {approx}5 times the original specification for CEBAF. The cryogenics plant will be roughly doubled and new rf systems will be installed for the new cryomodules. The beam transport system will strongly leverage existing hardware but must be enhanced with new power supplies, one new recirculation arc, and a beamline to the new Hall D. A brief description of the scope for the various accelerator subsystems will be given as well as the status of the project as a whole.
