[Sbs] [EXTERNAL] Time to sign up for shifts for the first SBS run group

[Cates, Gordon D (gdc4k)]

Dear SBS Collaborators,

The time has come to start signing up for shifts for the GMn (and GEn-RP, WAPP and nTPE) runs
that start in September.  The policy on shift requirements for authorship are described below, and a 
link is provided to the shift schedule.  Please note that you can get credit for shifts RIGHT NOW by 
coming to JLab and participating in the installation (more details below).  It would be a huge help!  
Also, ALL users must re-register with JLab if you have not done so already during the post-COVID era, 
and note that it takes about a week to get approval  to come on site.  Again, a link is provided below.

Please start signing up, and if possible, spending time at JLab to help with the installation!

Best regards,

Gordon Cates for the SBS CC

**********************  SBS authorship and shift policy   *************************
**************************************************************************************

The first SBS run group includes the GMn measurement (E12-09-019), as well as 
three shorter experiments (see below).  At least one primary paper is expected from
each of the four experiments.  The basic SBS Collaboration policy for insuring authorship on 
one or more experiments is as follows.  For authorship on all four (primary) papers, we ask 
collaborators to take at least 10 shifts, with the caveat that night shifts count as 1.5 shifts.  For 
authorship on only GMn, collaborators are asked to take at least 8 shifts, and for authorship on 
one of the shorter experiments, collaborators are asked to take at least 5 shifts.  Regardless of 
the specific experiment(s) on which you seek authorship, the shifts can be taken at any time during 
the first SBS run group.  You can sign up for shifts at:  
https://misportal.jlab.org/mis/apps/physics/shiftSchedule/index.cfm?experimentRunId=GMn-2021 <https://misportal.jlab.org/mis/apps/physics/shiftSchedule/index.cfm?experimentRunId=GMn-2021>

In addition to taking shifts during the SBS run, collaborators can also get credit for shifts by participating 
in the installation effort that is currently underway in Hall A.  With all the new SBS-related detector 
systems, and fewer people on site because of the pandemic, we are shorthanded preparing for the 
beginning of the run in September.  Please consider coming to JLab over the next several weeks to 
participate. In addition to helping insure a timely startup for the run, getting involved right now provides 
an excellent opportunity to become more familiar with all the SBS-related systems.  Each day worked 
will count as one shift.  

*** To join in the installation effort, please contact Bogdan Wojtsekhowski to coordinate your schedule with
the efforts that are going on in Hall A.
*** Note that ALL USERS need to re-register (if they haven't already)  for the post-COVID era, and approval
can take up to a week.  In fact, users will even lose remote access to their computer accounts if they do not
re-register by August 31st.  The process is slightly more involved if you are doing more than taking shifts during
the run, but still straightforward. You can register at:  https://misportal.jlab.org/jlabAccess/ <https://misportal.jlab.org/jlabAccess/>  .
Please contact Mark Jones if  you need further assistance.

The SBS Collaboration authorship policy also includes several variations on the basic policy stated
above. Anyone serving as run coordinator for at least one week will be considered as satisfying the 
requirements for authorship on all four primary papers.  Also, for individuals who have previously 
contributed in major ways to the preparation of the SBS experiments, a reduction of the required number 
of shifts will be considered on a case-by-case basis.  Finally, we note that the numerical shift requirement 
will in general be applied to research groups as a whole. That is, authorship will be granted to all members 
of a research group as long as the average number of shifts taken within that group satisfies the basic shift 
requirement; this assumes, however, that all members of the research group in question have indeed been 
active SBS collaborators. 

Lastly, we note that we strongly encourage all members of the Hall A collaboration to participate in the
SBS experiments.  Should it be the case that there are not enough shifts to meet the demand of those that
wish to participate, we plan to reduce the required number of shifts to better accommodate a larger number
of collaborators.

The three additional experiments in the first SBS run group:
*** The GEn-RP (recoil polarimetry) measurement (E12-12-012),   
*** Polarization Transfer in Wide-Angle Charged Pion Photoproduction (E12-20-008), and 
*** Two-Photon Exchange Contribution to the Electron-Neutron Elastic Scattering Cross Section (E12-20-010)
