Hall C technical staff have started removing the large concrete pad in Hall C. This raised floor was installed for the hypernuclear spectroscopy experiments (unofficially dubbed "Hashimoto Highway") and allowed the High Resolution Kaon Spectrometer and the High Resolution Electron Spectrometer to be moved around the hall as needed. Staff from the lab, Old Dominion University and Tel Aviv University have transferred most of the decommissioned CLAS back-angle time of flight scintillator paddles to new frames. These frames serve to store the scintillators in a compact fashion and will also support the detectors in Hall C, where they will be used for future experiments needing backward proton and neutron detection.

The Darklight cube has been removed and good progress has been made restoring the infrared machine. The ultraviolet machine has been vented and a piece of beamline removed to receive the ring resonator optical transport. Several FEL staff, as well as others from the lab, participated in a workshop at Fermilab on next generation light sources.

A new study has investigated the model dependence of meson resonance properties extracted from the Dalitz-plot analysis of three-pion photoproduction reactions on the nucleon. For broad or overlapping resonances, the meson properties from the isobar model are found to be rather different from those of the unitary model. The findings illustrate the importance of constraining the amplitude parametrization by the three-particle unitarity condition when extracting meson resonance properties, which will be relevant for the forthcoming GlueX experiment.

Fire Deaths at Work
Here at JLab, safety programs are in place to identify and eliminate similar hazards. When a Safety Warden or other JLab staff member conducts a monthly walk-through, always be respectful of the staffer's observations. When he or she insists on precautions that ensure safety items are accessible or chemicals are stored a certain way, these staffers are looking out for your safety and that of your co-workers. Whenever you are asked to perform a task, to change a procedure or to move items to meet safety guidelines, be willing to discuss the situation with the Safety Warden or staffer, so that together, you can quickly eliminate any hazards, while also improving your own work flow or space.

Tracking Thomas at JLab
Congratulations this week go to Samika Hawkins, who was the first to correctly identify the location for Sept. 26. Honorable mentions go to John Kelly, Doug Higinbotham, Ryan Bodenstein, Anusha Liyanage, Lori Zukerman, Keith Harding and Kelly Tremblay. Check out the Tracking Thomas webpage for a better view of his last location and this week's new mystery photo.
