The operation is controlled by many computers and computer interfaces. The basic operation evolves around a stored electron beam that is captured in a magnetic field inside a high vacuum chamber. This allows the electron beam to circulate for several hours. Using experimental apparatus the accelerator operator can cause this electron beam to produce very bright syncrotron light. This comittee approves the use of allotted beam time.
