Abstract

Geometry, engineering design and characteristics of an RF cavity and a tetrode power amplifier are described. They are parts of an RF system at the frequency of 181 MHz. The cavity has a copper clad stainless steel body and has Q of 42,500 and a shunt impedance of 9.0 MOhm. Two cavities have been successfully tested up to an accelerating voltage of 1.2 MV what is 30% over the design value. One of them is mounted into the Duke´s storage ring at Duke University. More than 20 RF cavities will be built and installed in a race track microtron-recuperator for FEL program at Novosibirsk. The RF power amplifier has a modular design. Several single tetrode modules can be easily combined in a high power unit. Two modules were used during cavity tests. A CW RF power of 300 kW was obtained from this unit. This type of tetrode modules will be used in different e^-e⁺ colliders and storage rings
