A view down the South Linac, one of CEBAF’s two sections of linear accelerator. In the foreground are cryomodules from the original accelerator design. The new C100 cryomodules were installed at the end of each section of linac.
The CEBAF accelerator delivered full-energy electrons on Dec. 14 as part of commissioning activities for the ongoing 12 GeV Upgrade project. Operators of the Continuous Electron Beam Accelerator Facility delivered the first batch of 12 GeV electrons (12.065 Giga electron Volts) to its newest experimental hall complex, Hall D.
