Description
The development of a fast electron beam switching system for Swiss Free Electron Laser[1] (SwissFEL) is in its final phase. Two high stability resonant kicker magnets followed by a septum should separate two closely spaced electron bunches (28 ns apart) and send them to two separate undulator lines. Extremely high shot-to-shot amplitude stability will ensure minimal shot-to-shot variation of the generated X-ray pulses. As previously reported, the prototype system met the project requirements, reaching 3 ppm rms shot-to-shot amplitude stability[2]. During final system optimization better than 1 ppm rms shot-to-shot amplitude stability (10e-6) has been achieved.
