Over 850,000 hours have been accumulated on the klystrons and modulators that constitute the LAMPF 805-MHz rf system. The 1-1/4 MW klystrons, the floating-deck modulators, and the modulator triodes are described. The operating data are summarized, and the fault and failure modes are tabulated for the three major components of the system. The high-voltage processing and other maintenance required to keep this 86-kV system operating reliably are described. The tube failure rates, tube fault rates, and modulator fault rates are presented. The mean time to failures is greater than 56,500 h for the klystrons and greater than 40,600 h for the modulator triodes. The steps taken to produce such good reliability are discussed.
