And then update the link in the agenda below by logging into the wiki, clicking the 'Edit' link
next to 'Preliminary Agenda' and replacing the 'TBD.pdf' file name associated with your talk below
to the filename you used.
Email your talk to Brad S or Xiaochao Z. if you have any problems.

Polarized He-3 Proposals
E12-06-110 (A1n)
Measurement of the neutron spin asymmetry A1n in the valence quark region using a 11 GeV beam and a polarized 3He target in Hall C
- E12-06-110 (A1n) proposal for PAC30 - detailed physics motivation and rates/uncertainties assuming the 6 GeV polarized 3He target performance
- E12-06-110 (A1n) Update for PAC36 - in this update we used the stage-II target upgrade performance - approved for 36 PAC days
- E12-06-110 (A1n) 2018 Update - in this update we summarize the rate and uncertainty estimation using the stage-I polarized 3He target and with the latest HMS and SHMS simulations, while keeping the total approved beam time (36 PAC days) unchanged. Some of the kinematic settings have been modified to reflect the latest status of the HMS or SHMS.
E12-06-121 (d2n-g2n)
- E12-06-121 (d2n-g2n) Proposal for PAC30
- E12-06-121 (d2n-g2n) Update for PAC36 (Grading PAC) - Approved for 29 PAC days. Updated to accommodate planned improvement in Target FoM.
E12-06-121A (Measurement of 3He Elastic Electromagnetic Form Factor Diffractive Minima Using Polarization Observables)
- Pol_3He_Elastic_Measurement
- 3He Form Factor Double-Polarization Asymmetry Measurement Proposal
