The Talk Coordinator (TC) is responsible for overseeing the equitable distribution of speaking opportunities to Members of the Collaboration.  The TC will look forward to future conferences and solicit invited speaker slots from conference organizers. Members who directly receive invitations from conference coordinators should coordinate their response with the TC.  It is the TCs responsibility to keep the collaboration aware of this and to encourage institutions to send junior researchers (students and postdocs).  The TC should communicate with collaboration members and labs and other funding opportunities to students with limited funding get the resources needed to give talks at upcoming events.  All people interested in giving a talk or poster using the analysis or any results from E1039 at a conference should get approval from the TC before doing so.  The TC will establish protocols for the review and approval of conference abstracts, presentations, and proceedings.  A web page archiving all collaboration presentations will be maintained by the TC.  The TC will also provide a meeting or phone meeting for practice talks upon request to get feed back from collaboration members.

When an analysis has reached an advanced stage and it is desired to make a presentation of preliminary results at a conference, the primary analyzers, in coordination with the Chair, Talks Coordinator, Analysis Coordinator and Physics Coordinator will form an open meeting to assess the quality and completeness. If it passes this initial review a presentation to the Collaboration will be given asking for "Preliminary Results" status for a Graph or Graphs of the results. A Graph of Preliminary Results should be as self-contained as possible, since it will likely appear in public archives of presentations and proceedings, and might be used by others outside the Collaboration. All such Graphs must contain the stamp "SpinQuest Preliminary" after approval. The Collaboration will only approve a single Preliminary Result for any particular physics observable; it is expected that a Final Result will appear in a near-term publication.  The Chair will coordinate the Collaboration evaluation in a Collaboration meeting. The Collaboration may vote to approve or reject with suggestions of improvement.

Critical Systems List:

The Physics Coordinator is responsible for forming the physics working groups with the Analysis Coordinator and Chair. The PC will organized all information acquired from E906 in regards to reconstruction, analysis and systematic uncertainty to improve the potential for physics extraction of SpinQuest. A note should be generated to contain all this information which should be presented for the Analysis Coordinator and the Collaboration use. The PC will keep track of all the physics goals and assign the collaboration members to a particular physics working group.  No work should be submitted for publication without collaboration approval, the PC helps to ensure this.  The PC is also the one who orchestrates this approval with the Chair. The Working Groups and Collaboration must all give approval so a Committee will be formed for a review of each potential publication and should pass both layers of the Review.  The PC sets the time frame of these reviews and manages the internal correspondence between the authors and reviewers. The PC is also responsible for helping to organize and carry out phone meetings on analysis and helps the Analysis Coordinator with the responsible for obtaining/maintaining resources for analysis, stable software (approved by collaboration), and reconstruction.

The Backup Run Coordinate helps the Run Coordinator with whatever is needed to help optimally run the experiment. There also are several on-site and off-site tasks and jobs that these coordinators should keep track of.  Some short term and some ongoing.  The Backup Run Coordinator (BRC) keeps track of these jobs and helps to find collaboration members to do them.  These jobs may be part of service work so the BR Coordinator can help to determine the value of the work done for each job listed as a Service Task.  This information should then be reported back to the Service Coordinator.  The BR coordinator must solicit jobs from the Run Coordinator and Spokespeople and Collaboration Coordinators to compile a list of jobs and people to do them continually. This is especially critical for operations and jobs having to do with experimental running.  They should then inform the Run Coordinator of up coming jobs and jobs with no one assigned.  The BRC should keep a website with the information on each job and the value of the job as service work for each posting as needed. The BRC should also oversee operations and the running of the experiment with the Run Coordinator and assist the Run Coordinator as needed.  The BRC serves as backup to the Run Coordinator and will become Run Coordinator in the next itteration.  The BRC should also designate the new BRC after they become RC.
