Free-electron coherent radiation in axial and helical magnetic fields
A detailed discussion is made on phase-space motion equations and radiation field equations for free-electrons near the magnetic resonance in the axial and helical magnetic fields. Red-shift spectral broadening and gain enhancement for free-electron radiation are obtained near magnetic resonance. Our theory is applicable to variable periodic and taper helical wiggler fields.
