12 GeV Upgrade
Construction of the five magnets for the Hall C Super High Momentum Spectrometer (SHMS) continues. Procurement of cold mass parts for the small horizontal bend dipole magnet has started in preparation for assembly of the finished coils. Winding of the fourth and last coil for the Q1 quadrupole magnet is complete, and preparation of magnet laminations is continuing. Soldering of the copper stabilizer to the superconducting SSC cable for the Q2, Q3 and dipole magnets is nearly complete. Production winding tooling for the dipole magnet has been assembled and used to wind a 1-meter prototype of the innermost dipole coil. The wheels and bogies for the support structure are being assembled and checked at the factory before shipment, and tenders for the assembly contract for the support structure are being readied. The several hundred tons of steel yokes for the Q2, Q3 and dipole magnets have been completed and shipped from the vendor and will arrive in about a month.
JSA Accepting Applications for 2013 Outstanding Nuclear Physicist Award
Center for Theoretical and Computational Physics
Electron scattering experiments at JLab with 6 GeV energy have established the existence of short-range nucleon correlations in nuclei - configurations in which protons and neutrons are much closer to each other than on average and experience strong short-distance interactions. A recent theoretical study predicts similar short-range correlations also between quarks in the proton, namely in the "sea" of quark-antiquark pairs that is created by the chromodynamic fields. These correlations have a distinctive effect on the proton's dynamical response and could be observed in high momentum-transfer experiments at 12 GeV or higher energies, opening up a new way of studying the role of Quantum Chromodynamics in hadron structure.

Tracking Thomas at JLab
Congratulations this week go to Ryan Bodenstein, who was the first to correctly identify the location for Oct. 3. Honorable mentions go to Harry Fanning, Jared Martin and Michael Martin. Check out the Tracking Thomas webpage for a better view of his last location and this week's new mystery photo.
