Abstract:

Reference documentation for the PolHe3 target polarization associated with the 2019-20 A1n and d2n experiments

See HallC wiki URL for additional details.

A1n_d2n_Gas_Densities-Huong-May2022.pdf has a summary of values for all cells except for Tommy. See 'TOMMY_density_and_uncert_final.docx' for that cell.

Cell TOMMY information updated.
Cell BRIANA information updated.
Cell AUSTIN information updated.
Cell BIGBROTHER information updated.
Cell DUTCH information updated.
Cell FULLA information updated.
Cell BUTTERBALL information updated.
