Shutdown begins June 15, preparations underway
A worker repairs the Electron Cooling Beamline Assembly in Main Injector Tunnel. Fermilab employees and contractors will conduct repairs, upgrades and regular maintenance during the Accelerator Complex shutdown beginning June 15.
The Accelerator Complex will shutdown June 15 after essentially 20 months of running.
The 11-week shutdown allows for a series of repairs, replacements and upgrades to the accelerator and detector components in order to keep the complex performing well.
Maintenance jobs account for the majority of the projects planned for completion during the shutdown. Four larger projects are also planned. Crews will remove dirt in order to punch a hole in the Main Injector ceiling to add conduits for NOvA, fix Tevatron magnets in six houses, place a drift tube in the Linac and replace 36 Booster corrector magnets.
"The shutdown is a huge event and requires the work of employees from divisions, sections and centers across the laboratory," said Bob Mau, head of the accelerator operations department. "We're going to pull employees from many parts of the laboratory, which means that responses to some normal requests will take longer than usual."
Although the shutdown will officially begin on June 15, the complex has already begun reducing beam and will shut of experiments and Accelerator Complex sections next week. Beam to NuMI, the Booster and the Main Injector will shut off on Saturday, June 13 and to the Tevatron on Sunday, June 14.
A series of power outages are also planned for the first to the master substation from 7-7:30 a.m. on Monday, June 22. More information about that and future outages will be available in Fermilab Today.
