SLED

The SLAC Energy Doubler / SLAC Energy Development

A scheme to improve the energy of the SLAC two-mile accelerator, SLED was developed by Perry B. Wilson, David Z. Farkas and Harry A. Hoag from 1973-1975 after their efforts were catalyzed by a "daydream" of Gregory Loew's, expressed in the final paragraph of his paper Electrons, The Energy Crisis and The Possibilities of RF Power in June 1973 (RLA52).

The radio-frequency pulse compression system boosts klystron peak power in order to increase the accelerator gradient.

The two SLED cavities can be seen directly above Loew, and the shiny box to the left of the cavities contains actuators used to "detune" the cavities.
