Abstract
The NAL booster - accelerator radio-frequency system design is described in detail. This rapid-cycling system is ferrite tuned from 30 MHz to 53 MHz. Each high-power module has an RF-output rating of 100 kW provided by a cascode amplifier which is a removable part of the cavity assembly. The low-level portion of the system corrects for both systematic and non-systematic tracking errors using a single set of wide-band beam sensors. In the design of a storage-ring RF system, the control of the beam-cavity interaction is a basic problem. This paper describes an arrange ment of TEM mode cavity, cascode power amplifier, beam pickup and feedback control loop to achieve a cavity-gap impedance of about 10 ohms over a frequency range from the synchrotron-oscillation frequency (a few Hz) to the higherharmonics of the bunch frequency. The design center radiofrequencyis 53.1 MHz.Keywords
