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. <b><i><span style="color:red">The deadline for submission of proposals and updates is 8:00 a.m. EDT (Eastern Daylight Time) on Monday, June 1, 2020.</span></i></b><o:p></o:p></span></p>

<b>All sections must be filled in.</b> 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,

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.<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt;line-height:normal">
<span style="font-size:12.0pt;font-family:"Times New Roman",serif">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.

<span style="font-size:12.0pt;font-family:"Times New Roman",serif">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.<o:p></o:p></span></p>
