The RF Accelerating System for the CERN PS Booster

In each of the four rings the acceleration will be provided by a single RF cavity consisting of two ferrite-loaded quarter-wave coaxial lines. The four cavities are superposed in the same straight section in order to save space for future developments, and are thus severely limited in height (< 360 mm). To help ensure high reliability, and ease of cavity replacement, forced air cooling was chosen. Ferrite biasing is achieved by means of two figure-of-eight loops. The final stage of the RF amplifier is located at the cavity while the driver and preamplifier stages are centralised. Special problems encountered are reported and the adopted solutions described.
