[Cuga] PAC40 Call for proposals- A message from Bob McKeown

[Lorelei Chopard]

*Program Advisory Committee Meeting -- PAC40***

December 14, 2012

PAC40 will be held during the week of June 17, 2013 and will continue the call for new
nuclear physics proposals. The PAC will judge the technical and scientific
aspects of submitted proposals and provide recommendations to Laboratory
management. New proposals will be recommended for approval only if they
represent high quality physics within the range of scientific importance
represented by the previously approved 12 GeV proposals.*/
The deadline for submission of proposals and updates is
8:00 a.m. EDT (Eastern Daylight Time) on  Monday, May 6, 2013./*

*/Proposals and updates for PAC40 should be submitted electronically using the instructions at
  /**/http://www.jlab.org/exp_prog/PACpage/instructions.html/*

*New Proposals***

Detailed information on the process for proposal submission is available at
http://www.jlab.org/exp_prog/PACpage/guidelines.html.  
New proposals will be granted a 20 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.

In the past, proposals from Hall B that would run in parallel with previously
approved proposals were separately considered by the PAC. Beginning with PAC40,
the Hall B collaboration should submit proposals for complete run groups at one
PAC meeting, where all of the anticipated physics associated with the proposed
run group will be considered. Each run group can submit up to 4 individual
proposals (up to 3 physics topics plus 1 summary of additional topics) and will
be granted a maximum of 4 presentations corresponding to these proposals. New
experimental proposals that run in parallel with previously approved run groups
should be considered internally by the CLAS12 collaboration. A CLAS12
representative will have the opportunity to report on these to the PAC, and the
PAC will then provide comments on them in its report. Proposed parallel running
in other halls should be handled in a similar fashion.

*Conditionally Approved Proposals***

The PAC may conditionally approve proposals when additional requirements must be
fulfilled before full approval is granted. There are two categories of
conditional approval:

·          C2 -- must return to the PAC to address concerns or issues to obtain approval,

·          C1 -- must meet designated technical requirements to obtain approval from laboratory
            management-- further PAC review is not required.

The rule for newly conditionally approved 12 GeV proposals is that they must return for approval at one of the
next 2 consecutive PAC meetings following the PAC at which they received the conditional approval status.

Proposals that received C2 status at a previous PAC may return to PAC40 to be considered
for approval. Proposals with previous conditional approval (C2)  that wish
to be considered for approval at PAC40 should submit an updated proposal and
will be granted a 20-minute presentation 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. If approved, the proposals will be considered for rating
along with the other approved proposals in the grading session.

*Prioritization*

As the backlog of experiments is now quite substantial and there are several years before the experimental program is
underway, we anticipate a need to establish a process to address priorities in the future. PAC40 will continue a discussion
of the process for re-establishing priorities of approved experiments on a timely basis.

*Prioritization of Run Groups*

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.

*PAC Results***

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 PAC40 website within 24
hours. The final written PAC report will be posted on the PAC40 website and the
user community notified by email as usual.
