Worldwide First EEHG Signal at a Storage Ring
the electron beam axis in the undulator U250 using motorized mirrors (in the following figure: M1, M2, P1, P2). The pulses are synchronized with each other by adjusting the path length (delay). The successful [...] harmonic generation) was proposed in 2009 as a method to improve the output of free-electron lasers [1]. Two laser pulses are used to manipulate accelerated electrons in such a way that short-wavelength …
