12 GeV Upgrade
One of the last civil construction tasks for the 12 GeV CEBAF Upgrade is the accelerator tunnel air conditioning. Under this contract, installation of the chilled water piping in the tunnel is now complete. Pressure testing of piping segments has begun. With successful pressure tests, the chilled water piping is insulated. Installation of fire sprinkler pipe in the tunnel arcs continues.
Center for Theoretical and Computational Physics
A new paper studies the transverse momentum dependent (TMD) evolution of the Collins azimuthal asymmetries in e+e- annihilation and semi-inclusive hadron production in deep-inelastic scattering (SIDIS) processes. By applying the TMD evolution at the next-to-leading-log order in the Collins-Soper-Sterman formalism, the transversity distributions for u and d quarks and Collins fragmentation functions are extracted from a global analysis of data on the Collins asymmetries in back-to-back di-hadron production in e+e- annihilation (from BELLE and BABAR) and SIDIS (from HERMES, COMPASS, and Jefferson Lab Hall A).
The electrical engineering systems group is working on:

Environment, Safety, Health & Quality
Resolving ES&H Concerns
The DOE DPO process ensures that all JSA employees and contractor employees have the right to report environment, safety, and health technical concerns that have not been resolved through routine work processes.
Once your concern has been addressed, communicate any lessons learned to your staff, co-workers, supervisors and your Division Lessons Learned Coordinator. ES&H Manual Chapter 2310 offers more information on concern resolution
