Description
Smith-Purcell radiation (SPR) was discovered to be generated from a metallic grating when an electron beam passes close to the grating's surface. These electrons induce a charge on the surface of the grating, whose periodic motion generates a source of radiation with wavelength related to the viewing angle with respect to the grating. Furthermore, SPR becomes coherent (CSPR) along the viewing angle for electron beams whose length are comparable or less than the period of the grating. This has allowed for CSPR to become a viable diagnostic tool for analyzing the profile distribution of the beam without inducing any change to the beam itself. I will conduct a basic overview of the theory behind SPR and how different distributions of electron beams can produce a variety of energy distributions. I will then review some of the methods conducted for reconstructing the profile distribution from CSPR and well as new computational methods that have been developed in recent years. Finally, I will cover plans for future CSPR experiments at the Helmholtz-Zentrum Dresden-Rossendorf laboratory and how we plan use these methods to further explore beam profile reconstruction.
