Plasma wave wigglers for free-electron lasers

Plasma Wave Wigglers for Free-Electron Lasers

We explore the possibility of using a relativistic plasma density wave as a wiggler for producing free-electron laser radiation. Such a wiggler is a purely electric wiggler with frequency w p (plasma frequency) and wavenumber k,,. If an electron beam is injected parallel to the plasma wave wavefront, it is wiggled transversely with an apparent wiggler wavelength X, = 27rc/wp. Using plasma densi...

Free-Electron Lasers with Electromagnetic Standing Wave Wimlers

Abstrucf-A detailed analysis of the electroniagnetic standing wave wiggler for free-electron lasers (FEL’s) is conducted for both circular and linear wiggler polarizations, following a single-particle approach. After determination of the unperturbed electron orbits in the wiggler field, the single-particle spontaneous emission spectrum and subsequently the gain in the low gain Compton regime (u...
