If you have time to think about another another hall C 12GeV proposal
consider joining this proposal. The abstract is below. The proposal
is at http://www.jlab.org/~jones/12GeV/deut.pdf . It needs some more 
work. If you want to be a collaborator send a email to jones at jlab.org
or boeglinw at fiu.edu .

                     Cheers,
                           Mark Jones

Abstract
--------

   We propose to measure the D(e,ep) cross section at Q2=4.25
   GeV2 and xbj=1.35 for missing momenta ranging from
   0.5 GeV/c to 1.0 GeV/c expanding the range of missing
   momenta explored in the Hall A experiment (E01-020). At these energy
   and momentum transfers
   calculations based on the eikonal approximation have been shown to
    be valid and recent experiments indicated that final state
   interactions are relatively small and possibly independent of
   missing momenta. This experiment will provide for the first time
   data in this kinematic regime which are of fundamental importance to
   the study of short range correlations and high density fluctuations
   in nuclei. The proposed experiment could serve as a
   commissioning experiment of the new SHMS together
   with the HMS in HallC. A total beam time of 21 days is requested.
