Jefferson Lab is preparing to upgrade its 6 GeV Continuous Electron Beam Accelerator Facility (CEBAF) to 12 GeV reach in energy. The energy doubling will significantly extend the scientific reach in the three existing experimental Halls A, B and C, and the upgrade will add the capability of a newly constructed hall, Hall D, to study the ‘confinement of quarks’. The energy upgrade will be achieved by the addition of ten high performance high gradient SRF cryomodules into existing space in the north and south recirculating linacs that will enhance the energy per pass to the level of 2 GeV. The SRF modules will be constructed at JLab with achieved gradients in excess of 20 MV/m and associated power RF and controls. The cryogenics will be upgraded by 50%, the transport magnets enhanced to deal with the increased beam energy, and a special radiator placed in the path of the electron beam to produce up to 9 GeV photons for Hall D physics. The present status of the 12 GeV Upgrade project will be described along with a hint of the science to be achieved.
