The FEL team has started in procurement activities funded by the Commonwealth of Virginia for capital improvements to the FEL injector and linac. Other efforts are mostly on hold, as most staff has been transferred to organizations with funding.
The Installation group has made significant progress installing girders and magnets in the transport channel recombiner. The Bcom-style magnets (multipass bending dipoles with one vacuum chamber) have been installed in the 1st recombiner,1st spreader and 2nd spreader. Six of the 25 quad girders that carry the beam from the end of the north linac to the Hall D tagger area have been installed. These girders are installed on stands with just a few inches of clearance from the tunnel floor.
Additionally, the installation folks have been working in the beam switchyard. The BSY girder and dipole removal for upgrade work has been completed. Pedestal grouting has been carried out throughout the machine. Low-conductivity water work is almost complete in the 1st recombiner, 1st spreader and has begun in the 2nd recombiner.
The Vacuum group completed warm region girder work in the linacs to support cryomodule commissioning. The group is also continuing installation of beamline pipe in Hall A. Additionally, the group is cleaning and leak checking vacuum chambers for various septa magnets. Work is almost complete on the rebuilding of the quadrupole girders. Finally, the Vacuum group supplied a Roots blower to support the Central Helium Liquefier and is repairing a broken blower for the cryo group.

RIM Trivia Question of the Week
Congratulations to Tim Nellis for his super-fast response to last week's question: The term that has come to mean network abuse via junk email and junk postings to message boards most likely originated from a skit during which a group of Vikings sing the following song in a cafe: "Spam, spam, spam, spam, spam, spam, spam, spam, lovely spam! Wonderful spam!" What is the name of the group that performed the skit? The answer was Monty Python.
