Injection Options for 12 GeV CEBAF Upgrade / Kazimi, Reza ; Benesch, Jay ; Chao Yu Chiu ; Grames, Joseph M ; Krafft, Geoffrey A ; Tiefenback, Michael ; Yunn, Byung C ; Zhang, Yuhong
Jefferson Lab is planning to upgrade the CEBAF accelerator from 6 to 12 GeV. In order to achieve this, the beam energy at injection into the main accelerator needs to increase from 67 MeV to either 123 or 134 MeV depending on the location of the new experimental hall relative to the accelerator.

Ion Back-Bombardment of GaAs Photocathodes Inside DC High Voltage Electron Guns / Grames, Joseph M ; Adderley, Phillip ; Brittian, Joshua ; Charles, Daniel ; Clark, Jim ; Hansknecht, John ; Lynn Stutzman, Marcy ; Poelker, Matthew ; Surles-Law, Kenneth E
The primary limitation for sustained high quantum efficiency operation of GaAs photocathodes inside DC high voltage electron guns is ion back-bombardment of the photocathode. This process results from ionization of residual gas within the cathode/anode gap by the extracted electron beam, which is subsequently accelerated backwards to the photocathode. [...]

Beam Physics for the 12 GeV CEBAF Upgrade Project / Merminga, Lia ; Benesch, Jay ; Bogacz, S A ; Chao Yu Chiu ; Freyberger, Arne ; Grames, Joseph M ; Harwood, Leigh ; Kazimi, Reza ; Krafft, Geoffrey A ; Spata, Michael et al.
Beam physics aspects of the 12 GeV Upgrade of CEBAF are presented. The CEBAF Upgrade to 12 GeV is achieved via 5.5 recirculations through the linacs, and the installation of 10 new high-gradient cryomodules. [...]

ELIC at CEBAF / Derbenev, Yaroslav S ; Alex Bogacz, S ; Chel Yunn, Byung ; Delayen, Jean R ; Grames, Joseph M ; Hutton, Andrew ; Krafft, Geoffrey A ; Li, Rui ; Merminga, Lia ; Montag, Christoph et al.
We report on the progress of the conceptual development of the energy recovering linac (ERL)-based Electron-Light Ion Collider (ELIC) at CEBAF that is envisioned to reach luminosity level of 1033-1035 /cm2s with both beams polarized to perform a new class of experiments in fundamental nuclear physics. Four interaction points with all light ion species longitudinally or transversally polarized and fast flipping of the spin for all beams are planned. [...]
