[PEPPo] 12 MSD

[Arne Freyberger]

Eric,
     I am not opposed to moving it out of the abstract.      The 
sentence was placed after the sentences that describe what we plan to do 
with Peppo and before the sentences that describe what will happen after 
the experiment.

The insertion of this sentence does make the abstract flow rather 
jerky.   The flow can be improved by removing the sentence that starts 
with "Following the demonstration....."    Which I think makes more 
sense since we never discuss what we will do following the experiment in 
the proposal.   New abstract:

    We propose to develop and install on the CEBAF injector a beamline
    and instrumentation
    appropriate for exploring the feasibility of a new approach for a source
    of polarized positrons: the transfer of polarization from an intense
    electron beam
    to positrons by a two-step process (bremsstrahlung followed by pair
    production) in
    a single target. Such a source would be an important enhancement of
    the scientific
    reach of the 12 GeV Upgrade, and has other uses ranging from high
    energy to condensed
    matter physics. This proposal requests two weeks of beam time
    utilizing the
    CEBAF injector which if scheduled during the first two weeks of the
    12 GeV CEBAF
    upgrade down will not impact the presently scheduled physics program
    but will require
    the CEBAF upgrade planning to include provisions for continued
    operations
    in the CEBAF injector for the first two weeks of the twelve month
    shutdown.



I had additional sentences on scheduling in the first paragraph of the 
Peppo run plan section (as you suggest) that are not in this latest 
release.  Not sure if this omission was an oversight or Larry felt it 
was redundant given the inclusion in the abstract.
