<p class="MsoNormal"><span style="font-family: "Times","serif";">PAC38
will be held
during the week of August 22, 2011 and will continue the call for
12 GeV
science proposals. As in the recent past, the criterion for approval of
new
proposals will be that the proposal represents "high quality physics
that,
based on what we know today, is highly likely to be of sufficient
scientific
merit that it will be included in the top half of the priority list to
be
established for the first 5 years of 12 GeV operations." <b><i>The
deadline for submission of proposals and updates is Friday, July 1,
2011.</i></b><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family: "Times","serif";">In
addition to
considering new proposals (in all categories), PAC38 will complete the
process
of assigning scientific priority and beam time to previously-approved
and
conditionally approved proposals by considering proposals in Category
4: "<span style=""> The 3D structure of the hadrons </span>".
<b><i>Updates to PAC38 for previously approved and conditionally
approved
proposals in Category 4 must be submitted no later than Friday, July 1,
2010.</i></b>
<span style=""> </span>Note that at this PAC and all future
PACs, the assignment of scientific priority and beamtime for new
proposals will
be made at the first PAC at which the proposal is accepted.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-family: "Times","serif";">Detailed
information
on the process for proposal submission is available at <a
href="http://www.jlab.org/exp_prog/PACpage/guidelines.html">http://www.jlab.org/exp_prog/PACpage/guidelines.html</a>.
Some details of the submission process have changed recently so please
read the
guidelines with care. Note that we no longer require identification of
a
contribution to construction of the base equipment in the 12 GeV
upgrade.
However you are encouraged to provide such identification as
appropriate and
this information may be useful to the PAC. Note also that experiments
may be
proposed that use either significant new ancillary equipment or major
new
apparatus. The proposal submission guidelines provide more details
about the
additional information required of such proposals. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family: "Times","serif";">New
proposals will
be granted a 30 minute presentation in a public session at the PAC
meeting. Following
the public presentation session the PAC will continue its discussions
in closed
session, and at least one spokesperson should be available either in
person or
by phone for 24 hours after the public session to answer questions as
the PAC's
discussion progresses. Proposals will, if approved, be given a
scientific
rating and a beamtime allocation. <o:p></o:p></span></p>

Proposals<o:p></o:p></span></h1>
<p class="MsoNormal"><span style="font-family: "Times","serif";">The
PAC may conditionally
approve proposals when additional requirements must be fulfilled before
full
approval is granted. There are two categories of conditional approval:<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-family: "Times","serif";">For
previously
approved proposals in Category 4, there will be an open grading session
to
facilitate scientific ratings and beamtime allocations. The session
will begin
with an overview/summary talk by a rapporteur. This will be a 45 minute
talk
summarizing the physics of the category, discussing each of the
approved and
conditionally approved proposals in the context of this category, and
addressing how the proposals complement/supplement/overlap each other.
The
rapporteur's summary will be followed by short presentations (three
slides
only, see below) by the spokespersons for each previously approved
experiment
in Category 4. <b style="">Spokespersons of each
experiment undergoing the prioritization review are asked to suggest
knowledgeable scientists who they would recommend as rapporteurs for
the
category of their proposal by Friday, March 4, 2011.</b> The rapporteur
would,
ideally, have no conflict of interest as a member of one or a few of
the
proposals in the category, or, alternately could be involved in all of
them. We
will identify the rapporteur well before the PAC meeting and ask them
to
provide all spokespersons with copies of their intended viewgraphs
prior to the
presentation so that spokespersons will have the opportunity for
constructive
criticism. The talk will, however, in the end, represent the
rapporteur's
judgment and thoughts. Following this public session the PAC will
continue its
discussions in closed session. At least one spokesperson should be
available
either in person or by phone for 24 hours after the public session to
answer
questions as the PAC's discussion progresses. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family: "Times","serif";">(Note
that
experiments in Category 4 that were conditionally approved at previous
PACs
will not be included in the public presentation session with the
rapporteur as

presentation to this PAC as part of the review of their conditional
approval
status.)<o:p></o:p></span></p>

of Run Groups<o:p></o:p></span></b></p>
<p class="MsoNormal"><span style="font-family: "Times","serif";">There
are a large
number of experiments (currently only in Hall B) that have been
organized into
"run groups". Run groups include multiple experiments that can take
data simultaneously on different and/or related physics using the same
detector, target, and beam conditions. In addition to the individual
experiment
ratings reviews discussed above for the experiments within the run
groups, we
will carry out a review of the run groups themselves to establish their
overall
scientific priority. This will be done in a PAC session roughly one
year before
CLAS12 starts taking data. If similar situations evolve in the other
halls we
will do a similar "overall scientific priority" assignment to the run
groups that evolve there. <o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-family: "Times","serif";">The
results of the
PAC's deliberations will become public as follows: the list of
scientific
ratings and beam time allocations will be provided to the Hall Leaders
at the
PAC closeout and then posted on the PAC38 website within 24 hours. The
final
written PAC report will be posted on the PAC38 website and the user
community
notified by email as usual.<o:p></o:p></span></p>
