COHERENT ELECTRON AND RADIATION PRODUCTION USING TRANSVERSE SPATIAL MODULATION AND AXIAL TRANSFER

摘要

Coherent electronic current is generated by generating and transmitting an electron bunch along a longitudinal axis. The electron bunch is then directed onto a target, wherein the target imparts a transverse spatial modulation to the electron bunch via diffraction contrast or phase contrast. The transverse spatial modulation of the electron bunch is then transferred to the longitudinal axis via an emittance exchange beamline, creating a periodically modulated distribution of coherent electronic current.
