12 GeV Upgrade
On Feb. 5, 2.2 GeV/pass tune beam was transported to 2R and held there for eight hours. This energy is a new record for one pass and is the machine performance needed to eventually deliver 12 GeV beam to Hall D and 11 GeV beam to Halls A, B and C. This demonstrates one of the Key Performance Parameters needed for CD-4A approval of the 12 GeV CEBAF Upgrade project. Starting from pre-calculated settings for the magnets, only minor adjustments were needed for the steering and optics. Beam transport installations for the accelerator are complete. The beamlines to the halls are being completed with vacuum checkout. The rebuilt YB septas in the east spreader/recombiner have been set back in place and are being hooked up and aligned. All radiofrequency and cryomodule scope has been completed. Box supplies for arcs 3-6 are onsite and at various stages of checkout. MARC5 and MARC6 are ready for testing with the dipole magnets. The final shipment of the 20 Amp trim supplies is on the way from the vendor. The Personnel Protection System installations for the 5.5 pass recirculation are complete. The order for the stripline beam position monitors has been awarded. Work is starting on the nano-Amp beam position monitors for Hall D.

Environment, Safety, Health and Quality
At Jefferson Lab, there are a wide variety of gloves available in the Stock Room that have been selected for the type of hazards at the lab. As one can imagine, there is no one glove for all hazards, so the supervisor in consultation with Industrial Hygiene has selected the type of glove for a particular job. The type of glove is specified in the various work control documents for that work. "Rubber" gloves, a poorly used generic name, is applied to numerous types of soft, pliable-material gloves, but each has distinct chemical resistance properties. Therefore, it is important to use only the glove specified, and in the correct size and in good condition, for a particular chemical so that you avoid a skin injury. For more information regarding glove selection, consult the ES&H Manual.
