Design and Performance of the Slac Drive System
This paper describes the design and performance of the RF drive system of the Stanford Two-Mile Linear Accelerator. The function of this system is to supply a drive signal of 240 watts to each of the 240-24 MW klystron amplifiers whose power accelerates the beam. The following sub-systems are discussed: A highly stable tunable master oscillator at 476 MHz, a 17.5 kW CW main booster amplifier, a two-mile temperature stabilized 3-1/8 inch diameter main drive line, 30 times-six varactor frequency multipliers, 30 pulse modulators and sub-booster klystrons, 30 temperature stabilized 1-5/8 inch diameter subdrive lines, isolator-phase shifter-attenuators used before each sub-booster and 24 MW klystron, the phase-stable interconnecting cables, and standby equipment.
