Linac and Booster:
Operators ran and tuned Linac and Booster beam over the weekend of June 28.

Main Injector and Recycler:
RF experts began running the Main Injector RF system, and operators have been monitoring the run. Main Injector tunnel work continues. First beam to circle the Main Injector is scheduled for this month.

Operators installed all the Recycler focusing and defocusing gradient magnet shims—for 213 magnets in all. The shims affect the field at the end of the magnet, helping shift the Recycler beam’s base tune and chromaticity.
