Four to Beam Up

Image courtesy of DOE’s Jefferson Lab - The cylindrical device seen here, called a separator, is one of several technological advances that allow CEBAF to simultaneously deliver electron beams to its four different experimental halls.

For the first time, Jefferson Lab’s Continuous Electron Beam Accelerator Facility delivers beam to all four of its experimental areas simultaneously.

The Science

For the first time, Jefferson Lab’s Continuous Electron Beam Accelerator Facility delivered beams for experiments simultaneously to all four of its experimental halls: Halls A, B and C, as well as its newest hall, Hall D.

The Impact

CEBAF’s new four-hall capability allows it to deliver more efficient execution of approved experiments, while reducing cost per experiment. For instance, four-hall operation allows CEBAF to deliver beam simultaneously to four experiments, rather than just three.

Summary

The Continuous Electron Beam Accelerator Facility (CEBAF) at Jefferson Lab in Newport News, Va., is the world’s most powerful microscope for studying the nucleus of the atom, serving more than 1,500 scientists worldwide who come to Jefferson Lab to conduct research. Since its first experiments in 1995, CEBAF has had the capability of delivering beam to all three of its original experimental halls simultaneously for research. A fourth experimental hall was added to CEBAF as part of a facility upgrade that was completed in September 2017. Adding the fourth hall to this simultaneous beam delivery system required a new operating paradigm and hardware made possible by clever advances in equipment and capability. This new four-hall simultaneous beam delivery capability allows CEBAF to more efficiently execute approved experiments, while reducing cost per experiment.
