Abstract

Nowadays in VUV-FEL accelerator the superconducting cavities made of niobium are filled with electromagnetic field necessary for electron bunch acceleration. The energy for electron is delivered from the high power microwave klystron tube. According to the project requirements the power level that should be achieved from the klystrons are only possible to achieve when tube works near to the saturation point. As almost every high power amplifier also this microwave tube amplifier behavior is strongly nonlinear in this work area. In the publication the method for the klystron and whole high power chain nonlinearities characterization is described. Also some propositions for online nonlinearities measurement and for klystron linearization in the VUV-FEL accelerator are discussed.
