Since constructing the R1 drift chambers for the CLAS12 upgrade, the group has been preparing for upcoming experiments by focusing on simulations to optimize run conditions. A program to optimize CLAS12's ability to detect pions is currently underway. Three components of this effort currently at various stages of completion are to incorporated a dual polarized target geometry into the official CLAS12 simulation,  quantify the moller electron background for beam pipe shielding, and improve the vertex reconstruction for a dual polarized target.  The geometry and materials for polarized target to be used in an upcoming experiment in JLab's Hall B has been completed and is being incorporated in the Hall's monte-carlo distribution.  The background from Moller scattering in Hall B has been simulated and is now guiding the design of beam line shielding elements with the results to be reported in a graduate student thesis this year.  A second graduate student has begun work on adapting the tracking software to accommodate reconstructing vertices when using the above dual polarized target.  These three efforts will be used to optimized data taking in JLab's Hall B during the Fall of 2020.

2.)If any of you are needing to submit NSF project reports (or whatever
 +
the equivalent is for the DOE), you may have seen the new regulations
 +
regarding the Public Access requirement - this essentially
 +
requires that the U.S. public be provided free access to scientific papers
 +
published arising from U.S. Federal taxpayer dollars, eg. NSF or DOE
 +
grants. The NSF has set up a Public Access Repository,
 +
( https://par.nsf.gov/ ) which is supposed to seamlessly interact with
 +
the DOE/OSTI E-Link system; these are where final published versions
 +
of the papers can be uploaded to, and where the public is then able to
 +
access them.
 +
 +
  What about our Nature paper? Isn't it embargoed (i.e. we can't
 +
upload the final version to the arXiv for six months) as part of
 +
Nature's business model? Can/should we upload it to NSF_PAR?
 +
 +
  Wouter and I had our annual report for our NSF grant due, so
 +
I looked into this. It turns out that if you upload to NSF-PAR
 +
using the DOI (Digital Object Identifier) for our paper
 +
(our DOI 10.1038/s41586-018-0096-0 ), Nature automatically supplies
 +
the metadata for the paper, which includes an embargo, i.e. the paper's
 +
title and author list are posted, but it states "This content will become
 +
publicly available on May 1, 2019" (see
 +
https://par.nsf.gov/biblio/10062439-precision-measurement-weak-charge-proton ).
 +
 +
  I am not sure if you can somehow link this to your own annual report;
 +
I am trying to discover this....
 +
 +
  One small irritation I uncovered: the metadata from Nature doesn't
 +
have the author list in the format required by NSF-PAR. I had to
 +
manually convert it; for your convenience, I have appended the correctly
 +
formatted author list to this email.

Since constructing the R1 drift chambers for the CLAS12 upgrade, the group has been preparing for upcoming experiments by focusing on simulations to optimize run conditions. A program to optimize CLAS12's ability to detect pions is currently underway. Three components of this effort currently at various stages of completion are to incorporated a dual polarized target geometry into the official CLAS12 simulation, quantify the moller electron background for beam pipe shielding, and improve the vertex reconstruction for a dual polarized target. The geometry and materials for polarized target to be used in an upcoming experiment in JLab's Hall B has been completed and is being incorporated in the Hall's monte-carlo distribution. The background from Moller scattering in Hall B has been simulated and is now guiding the design of beam line shielding elements with the results to be reported in a graduate student thesis this year. A second graduate student has begun work on adapting the tracking software to accommodate reconstructing vertices when using the above dual polarized target. These three efforts will be used to optimized data taking in JLab's Hall B during the Fall of 2020.
