Abstract

The 101 MHz RF amplifiers for a RFQ, an IH-structure and two bunchers for the CERN Lead Injector were provided by GSI Darmstadt. The accelerating structures required amplifiers up to 400 kW while the bunchers needed about 2 kW, both with a pulse length of 1 ms at a repetition rate of 10 Hz. The special properties of the amplifiers, technical difficulties and their cure in respect of RF-circuits, output coupling, parasitic oscillations of the final stage and fulfillment of the new CE standards are reported. A second part of the report describes the low level RF-circuits which were built by CERN
