Can I read High-Gain OAM Generation in FELs on EtoBox?
High-Gain OAM Generation in FELs by Particle Beam Physics Lab is a document available to read on EtoBox.
What is High-Gain OAM Generation in FELs about?
1) The document describes a scheme to generate intense coherent light carrying orbital angular momentum (OAM) at the fundamental wavelength of an x-ray free-electron laser (FEL). 2) In the scheme, the electron beam distribution is prearranged using a helical undulator and laser seed to induce helical microbunching in the beam. 3) This helically microbunched electron beam is then sent through an undulator, where it will radiate coherent light at the fundamental frequency with an OAM determined by the imp
