Positrons at Jefferson Laboratory

We review the compelling case for establishing a capability to accelerate positrons at Jefferson Lab. The potential appplications range from the study of two-photon exchange and deeplyvirtual Compton scattering to exploiting the charge current weak interaction to probe the flavor structure of hadrons and nuclei. There are also fascinating ideas for using such a capability to discover new physic...

A Proposal for the DarkLight Experiment at the Jefferson Laboratory Free Electron Laser

New theories of dark matter predict A gauge bosons in the mass range of 0.01– 10 GeV that couple to charged fermions with a strength of α /α EM = 10 −4 of the photon or less. We propose to design, construct and operate an experiment called DarkLight (Detecting A Resonance Kinematically with eLectrons Incident on a Gaseous Hydrogen Target) to use the 1 MW 100 MeV electron beam at the Jeffer-son ...

THE CONTINUOUS ELECTRON BEAM ACCELERATOR FACILITY: CEBAF at the Jefferson Laboratory

■ Abstract The Jefferson Laboratory’s superconducting radiofrequency (srf ) Continuous Electron Beam Accelerator Facility (CEBAF) provides multi-GeV continuouswave (cw) beams for experiments at the nuclear and particle physics interface. CEBAF comprises two antiparallel linacs linked by nine recirculation beam lines for up to five passes. By the early 1990s, accelerator installation was proceed...
