12 GeV Upgrade
The first of seven superconducting spectrometer magnets being built as part of the 12 GeV CEBAF Upgrade project has been delivered to Jefferson Lab. The first quadrupole magnet (Q1) for the Super High Momentum Spectrometer in Hall C is a clone of the High Momentum Spectrometer Q1 magnet; a cold iron design with a 40 cm warm bore, 11 GeV/c performance and a gradient of 7.9 T/m. It was built by Scientific Magnetics, Inc., in the UK and arrived on site on Jan. 13. Acceptance tests are underway. The Physics Division is convening an equipment readiness review for the new Q1 on Jan. 21 to assess the readiness for full, safe operation.

The XYZ peaks in the quarkonium spectrum found in recent experiments may be a manifestation of new quark resonances. If so, they cannot contain valence quarks only. Attempts have been made to explain them in terms of meson-meson molecules or multi-quark bound states. A new paper investigates the possibility that these peaks originate from anomalous thresholds related not to new hadrons, but to exchange forces from normal, open-flavor mesons.

The Machine Shop also completed various small machining jobs for lab customers.

What Is Safety?
At Jefferson Lab, we try to eliminate this middle area. It should always be true, no matter your level of experience, that you to stop to think or step back to ask, "What is going to happen when I do XYZ?" Every day and almost every job has some slight variable that changes the activity.
Safety is your frame of mind and how you approach that work.
