Title

Part of the Advanced Light Source storage ring

Description

Part of the Advanced Light Source storage ring. The Advanced Light Source storage ring is roughly circular with 12 arc-shaped sections (about 10 meters long) joined by 12 straight sections (about 6 meters long). The electrons coast for hours at constant energy inside an aluminum vacuum chamber where the pressure is about one trillionth that of the atmosphere. Hundreds of precision electromagnets (blue, yellow, and orange in the photograph) focus and bend the electron beam as it circles the storage ring more than a million times a second. The synchrotron light emitted by the electrons is directed to beamlines through the round beam ports.
