19 CHL-2 Upgrade magnets and power supplies Jefferson Lab in few years… Enhance equipment in existing halls add Hall D (and beam line) : Construction (funded at 99% by DOE- cost 310 M$) May GeV Accelerator Shutdown starts May 2013 Accelerator Commissioning starts October 2013 Hall Commissioning starts Pre-Ops (beam commissioning) E max Hall A,B,C: 10.9 GeV E max Hall D: 12 GeV Luminosity (A,B,C): ÷10 38 CLAS12

20 The primary goal of experiments using the CLAS12 detector at energies up to 12 GeV is the study of the internal nucleon dynamics by accessing the nucleon's transverse momentum (TMD's) and generalized (GPD's) parton distributions functions. Towards this end, the detector has been tuned for studies of exclusive and semi-inclusive reactions in a wide kinematic range. HALL B Physics Program (see M.
