Abstract
The theory of electron and positron channeling and radiation production in crystals has been extended to macroscopic-scale systems. The new theory, named QCP theory (quasi-channeling phenomenon), examines macroscopic systems that exhibit periodicity along the axis of beam propagation, specifically, periodic electrostatic fields; the dimensions of the field periodicity (lz) are much greater than typical interatomic lattice spacing (lL), e.g., lz≫lL, but much smaller than a typical wiggler wavelength lw, e.g., lw≫lz. The feasibility of a laser based on this predicted new phenomenon is examined in this letter. Differences between the properties of the proposed quasi-channeling radiation and radiation produced by wigglers and free-electron lasers (FEL’s) are discussed. System lengths a factor of 103 shorter than FEL’s are expected, with favorable scaling for below 500 eV laser photon output energies. A 500-eV QCP laser system with a gain of 1 and a length of 1 m is predicted, based on extrapolations of existing storage-ring technology.
