12 GeV Upgrade
All of the beam transport scope has been completed, with the exception of final leak checks in the Hall D tagger vault. All of the 20 Amp trim supplies for 5.5-pass beam have been checked and installed. Status of box power supplies: RSEP9 and arc 7 are ready to be certified for the Personnel Safety System and hooked up to the dipole magnets; arc 9 has been received and is being uncrated; and RSEP8 and arc 8 are nearly ready for PSS certification. The PSS system is ready for certification of the Hall D branch. The stripline beam-position-monitor electronics are being installed on the beamline to Hall D. A 4.8 GeV beam has been to the end of arc 6, and 3-pass 4.8 GeV beam has been sent to the Hall A dump.

RIM Trivia Question of the Week
Center for Theoretical and Computational Physics
A new Theory Center paper presents a method for analysis of Dalitz plot distributions based on the duality hypothesis, whereby cross channel resonances are responsible for direct channel backgrounds. Resonance contributions are represented through the associated Regge trajectories, which provide the dynamical link between individual partial waves. The amplitude is based on the Veneziano model, which features a high degree of degeneracy, and a method for breaking this degeneracy while preserving Regge asymptotics. The method is illustrated for vector charmonium three-pion distributions, but can be also applied to the decays of light mesons, such as η or ω, which are of interest to the Jefferson Lab spectroscopy programs.

Environment, Safety, Health and 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.
