Reconstruction of Energy Distributions in Electron Beams on the Basis of Bremsstrahlung X-Ray Spectra

Bremsstrahlung X-rays produced at the collector can be used for definition of electron energy distributions in gyrotrons and maybe in other high-power microwave devices. Such a possibility underwent early testing at the Karlsruhe Institute of Technology on two gyrotrons. Electron energy distributions calculated on the basis of X-ray spectra measured near the gyrotrons operated at different regimes have plausible shapes and demonstrate good correlation with expected characteristics of the electron beam, thus confirming the viability of the proposed diagnostic technique.
