Abstract

A new on-chip light source configuration has been proposed, which utilizes the interaction between microwave and a dielectric nanopillar array to generate a periodic electromagnetic near field, and applies periodic transverse acceleration to relativistic electrons to generate high-energy photon radiation. Here the dielectric nanopillar array interacting with microwave acts as the electron undulator, in which the near field drives electrons to oscillate. When an electron beam operates in this nanopillar array in this light source configuration, it is subjected to a periodic transverse near-field force, and will radiate X-ray or even gamma-ray high energy photons after a relativistic frequency up-conversion. Compared with the laser-dielectric undulator based on the interaction between strong lasers and nanostructures to generate a plasmonic near field, this configuration is less prone to damage during operation.
