Abstract

Ferrite loaded radio-frequency (rf) cavity with resonant frequency of several MHz is commonly used for proton synchrotrons. The high-intensity proton synchrotron like the JHP (Japan Hadron Project) requires high accelerating voltage at the maximum repetition rate of 50Hz. In order to select or develop ferrites which meet these requirements, a high power ferrite test bench was fabricated.<br>This paper presents the theoretical relations between ferrite properties and characteristics of rf cavity. Next, description is made for the fabricated test bench which consists of a test cavity, a measuring system, a bias power supply and an rf power supply. Three ferrites with large diameter over 500mm were successfully tested by 1kW rf input power and data equivalent in actual operation of rf cavity were acquired. As a result, usefulness of the test bench was verified.
