12 GeV Upgrade
In Hall B, the magnet support legs were installed and the bases grouted on the Torus magnet. The plan is for the “spit,” which has served as the temporary support for the magnet during the coil installation phase, to be removed later this week.
With snow falling and Jefferson Lab about to close early, on Friday, Jan. 22, the Horizontal Bend magnet in Hall C successfully reached a major goal following months of analyses, testing and review. After “training” at lower currents, the magnet was operated at 4,000 Amps, the current required for running the new Super High Momentum Spectrometer at its highest momentum.

The Electrical Engineering Group is working towards the restoration of CEBAF and the start of the spring run. Of particular note is the work of the RF group, looking at maximizing the accelerating gradients available to the machine, whilst solving some of the problems of reliability in the system and reducing trip rates. The I&C (Instrument and Controls) group has been commissioning the new fast feedback system in the Hall D line, which will be tested with beam in the upcoming run. The DC power group continues its project work and has started to turn on magnet 'box' supplies as part of Hot Checkout. The Safety Systems group has also been working through HCO for CEBAF, as well as project work in the halls. The electricians and 'fab shop' continue to support many projects, including the I&C system in Hall B.
It would be remiss to not include the departure of two lab employees during the past few weeks, the loss of over 50 years of combined experience at the lab. Bill Merz has retired after 22 years. He came to the lab in 1994 after working at Fermilab. Bill had an immense wealth of knowledge and experience in power supply systems, operations and management, culminating in his position as department head of EES. Ron Lauze has also retired after 29 years. He came to the lab in 1987, one of the first wave of employees via Lawrence Livermore. Ron had a number of roles throughout the years in operations and engineering, ending up as EES deputy department head. They will be missed both professionally and personally by many, and we wish them a long and happy retirement.

January 2016 Snowstorm
Just think, if the storm track had been 150 miles further south, we would have been in the same conditions as the Washington, DC area, with many more inches of snow/ice and stronger winds. Could you have coped with those problems? Use this latest storm as a personal "lesson learned" for how you can prepare better for the next snow.
