[Cuga] PAC46 Call for Proposals- a message from Bob McKeown

[Lorelei Carlson]

PAC46 will be held during the week of July 16, 2018 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, June 4, 2018.*

*/Proposals and updates for PAC46 should be submitted electronically 
using the instructions at 
/**/http://www.jlab.org/exp_prog/PACpage/instructions.html/*

*Please note:*that some changes have been made to the submission process 
which can result in your submission being considered incomplete and 
ineligible for review at the next PAC meeting.One of such changes is the 
completion of the coversheets.You will be prompted to complete each 
entry. All sections must be filled in. In some cases, you may answer N/A 
(not applicable), and this data will be reflected in your final proposal 
submission. There will be no follow-up queries from the Laboratory. If 
N/A is not appropriate for the proposal, it could result in the proposal 
being rejected for insufficient information. Also note that proposals 
which require new experimental equipment *must* include additional 
information. See http://www.jlab.org/exp_prog/PACpage/guidelines.htmlfor 
more details.

*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. Newly approved stage II (i.e., those using existing and/or 
funded equipment) proposals will also be considered for “High Impact” 
status for scheduling priority, as per PAC41.

New run group proposals (i.e., those requesting new beamtime) are 
defined as collections of proposed experiments that use common beam time 
and experimental equipment. Proposals for complete run groups should be 
submitted 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. The PAC may consider 
each of these for grading, but will attempt to provide a common 
assessment of the whole run group.

*Additions to Previously Approved Run Groups*

New experimental proposals that do not require additional experimental 
equipment and that run (even partially) in parallel with previously 
approved run groups should be considered internally by the proposing 
collaboration. Run group additions that require changes or additional 
equipment need to be submitted as full stand-alone proposals. Exceptions 
that require only minor changes or additions to the experimental 
equipment need to be discussed with the Associate Director for 
Experimental Nuclear Physics before submission to the PAC as run group 
additions. It is also requested that documentation (e.g., proposal and 
report) from the internal collaboration review be submitted to the PAC 
for their information. A collaboration representative will have the 
opportunity to report on these additional parallel running proposals to 
the PAC, and the PAC will then provide comments on them in its report.

*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; a 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 with previous conditional approval (C2) that wish to be 
considered for approval at PAC45 should submit an updated proposal and 
will be granted presentation time 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.

*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 
PAC46 website within 24 hours. The final written PAC report will be 
posted on the PAC46 website and the user community notified by email as 
usual.
