Spin-polarized free electron beam interaction with radiation and superradiant spin-flip radiative emission

Blog Article

The problems of spin-polarized free-electron beam interaction with electromagnetic wave at electron-spin resonance conditions in a magnetic field and of superradiant spin-flip radiative emission are analyzed in the framework of a comprehensive classical model.The spontaneous emission moen finney of spin-flip radiation from electron beams is very weak.We show that the detectivity of electron spin resonant spin-flip and combined spin-flip/cyclotron-resonance-emission radiation can be substantially enhanced by operating with ultrashort spin-polarized electron beam bunches under conditions of superradiant (coherent) emission.

The proposed radiative spin-state modulation and the spin-flip radiative emission schemes can be used for control and noninvasive diagnostics of polarized electron/positron beams.Such schemes are of relevance in important scattering experiments wilds of eldraine prerelease guide off nucleons in nuclear physics and off magnetic targets in condensed matter physics.
