Jefferson Lab Future Initiatives

With the scientific program at the Thomas Jefferson National Accelerator Facility (Jefferson Lab) in robust operation, it is time to plan for future developments of the facility. A new round of upgrades to the laboratory are under technical development. One of these is a potential energy upgrade to 22 GeV using novel magnet designs in the existing recirculation arcs. Another is a potential for intense polarized beams of electrons or positrons, which would allow for new measurements in nucleon tomography, and provide precision extraction of contributions from higher order electromagnetic currents. Still another is the possibility to open new beam delivery areas using secondary beams of muons, neutrinos and neutrons. In addition, advanced detector systems such as the Solenoidal Large Intensity Device (SoLID) are anticipated. A status for each of above efforts will be presenred, with some discussion of the physics opportunities for each.
