Free-electron laser inverse-Compton interaction x-ray source

The Quantum X-ray Compton Free Electron Laser

The quantum operation mode in the X-ray Compton free-electron laser (FEL) is presented. This FEL mode emerges when the quantum emission exceeds the electron beam energy spread and FEL homogeneous linewidth, determined by the optical undulator length. Such a FEL becomes a two-level quantum oscillator with a completely inverted active medium. In the nonlinear interaction regime, inversion can be ...

Higher harmonic inverse free-electron laser interaction.

We expand the theory of the inverse free electron laser (IFEL) interaction to include the possibility of energy exchange that takes place when relativistic particles traversing an undulator interact with an electromagnetic wave of a frequency that is a harmonic of the fundamental wiggler resonant frequency. We derive the coupling coefficients as a function of the IFEL parameters for all harmoni...

Compact Hard X-ray Source via Inverse Compton Scattering Based on the X-band Linac

We are designing a compact inverse Compton scattering hard X-ray (33 keV) source based on X-band linac. X-band 1.5and 3.5-cell photocathode RF guns and X-band linac were analyzed with PARMELA simulation, and X-ray flux was estimated for several types of lasers. The theoretical scaling law of the RF guns among charge, emittance, and RF wavelength is confirmed by PARMELA. The maximum RF field at ...

High-intensity double-pulse X-ray free-electron laser

The X-ray free-electron laser has opened a new era for photon science, improving the X-ray brightness by ten orders of magnitude over previously available sources. Similar to an optical laser, the spectral and temporal structure of the radiation pulses can be tailored to the specific needs of many experiments by accurately manipulating the lasing medium, that is, the electron beam. Here we repo...
