Abstract

An induction linac is being studied and built at CESTA (Centre d´Etudes Scientifiques et Techniques d´Aquitaine) for FEL (free-electron laser) application. The high-voltage (HV) generators and the induction cells were studied. A HV generator design to feed the cells with calibrated pulses (150 kV, 50 ns, Delta V/V<1%) has been built using a charging resonant system and magnetic switches. This generator is planned for kHz repetition rate operation. A prototype induction cell has also been built and tested with a cable generator. An electron injector (1.5 MeV, 1.5 kA) has been designed. It uses ten induction cells and a thermionic dispenser cathode. Numerical codes have been developed and simulations have been compared with experimental results for HV generators, induction cells, and injector.<>
