| 内容記述 | A compact cavity for acceleration has been developed with cobalt-based amorphous cores, which is a part of research and development (R&D) for a synchrotron in a cancer therapy facility. This core has high permeability that enables the cavity length to be made short, and its low Q-value of about 0.5 permits an RF system without tuning control of the cavity. The developed acceleration cavity consists of two acceleration gaps; at both sides of the gap there are quarter-wave coaxial resonators. The total length of the cavity is as short as 1.5m and the inner diameter of the vacuum chamber is 190 mm. Considering the requirements for easy operation and maintenance, a transistor RF amplifier was used instead of the commonly used tetrode in the final stage. Each resonator has a maximum impedance of 400O at 2MHz, and a 1:9 impedance transformer has been attached to use a solid state amplifier of 50O output impedance. In the frequency range from 0.4 to 8 MHz, an acceleration voltage of more than 4 kV can be obtained with a total input RF power of 8 kW. In this paper the structure of the cavity, the obtained core impedance, and their performances under high-power test are presented. | |||||
