Abstract
The principles of quantum-wiggler electrodynamics (QWD) are explained. Based on QWD, we confirm that in the Smith-Purcell configuration, the power of the radiation driven by the wiggling force acting in the beam’s direction (‘free-electron two-quantum Stark (FETQS) radiation’) is independent of the transverse wiggling whereas the power of the radiation driven by the wiggling force acting in the direction perpendicular to the beam’s direction (‘free-electron two-quantum magnetic-wiggler radiation’) is proportional to the square of the transverse wiggling velocity, ˜v 2⊥ . Because ˜v⊥ ∝ 1/γ, we find that the ratio of the radiation power of a free-electron radiation device using a magnetic wiggler to that using an electric wiggler scales as 1/γ2.
