Abstract :
The 100-MeV linear accelerator operating in stored energy mode is described. It is designed to inject the electron beam (with 15-ns pulse duration and 200-mA current within 1% energy spread) into the booster ring. The linac design is based on the 2.8-GHz DAW structure with three radial stems. The developed construction is easy to fabricate and tune and provides a good shunt impedance of 92 M Omega /m, the working frequency domain is free of high-order modes. The structure consists of a single 6-m-long section. The accelerator has a simple injection system without a special buncher. A nonbunched 40-keV beam formed by a diode gun is injected directly into the first DAW cavity. The focusing system is also simple.<>
