Abstract
- An X-band FEL study with the beam energy of 2.0 MeV are undergoing now. In order to get a low beam emittance at the beam current of 1kA, the diode design of 1kA in JAERI Large current Accelerator Induction Linac is carried out by EGUN code. To avoid electric discharge on the upper part of wehnelt electrode, the diode chamber and the wehnelt radius are designed under the radial electric field Er of less than 180 kV/cm. The diode chamber size of a φ508 mm diameter and the wehnelt diameter of φ188 mm are decided. In the optimized diode design, the beam current of 1kA and the normalized emittance of 2.5×103 π mm-mR are obtained. [ABSTRACT FROM PUBLISHER]
