12 GeV Upgrade
The first part of the Dipole magnet for the Super High Momentum Spectrometer (SHMS) was delivered to Hall C early in June. The CCR, or Cryogenic Control Reservoir, was fabricated in Illinois but has spent recent years in France, where it has been customized for the dipole by the magnet company, Sigmaphi. This vendor continues to work on sealing and leak-testing all three of the magnets they are building for Jefferson Lab. In Hall C, handrails have been installed on the concrete block that will become the roof of the SHMS shield house, and the vacuum connection between the first two SHMS magnets has been completed. Installation of the permanent cryogenic gas lines on the new spectrometer continues.

During the last quarter century, chiral effective field theory has been widely used for the derivation of nuclear forces and electroweak currents. Such a theory provides the most general scheme accommodating all possible interactions among nucleons, Δ isobars and pions compatible with the relevant symmetries — in particular, chiral symmetry — of low-energy quantum chromodynamics, the underlying theory of strong interactions. A new paper describes the construction of classes of chiral two-nucleon potentials, which are local in configuration space and are therefore suitable for use, in particular, with quantum Monte Carlo methods. These are applied to a calculation of binding energies of nuclei with mass numbers A = 3, 4 and 6.
