Abstract :
The presented analyzer of electron beam characteristics Soffron60 was designed for operation with GESA electron-beam material-treatment facilities, and can be used at machines with similar characteristics (~60 kV, ~100 A, ~100 μs, 0.1 T). The apparatus allows to determine spectra of two electron energy components with resolution in space and time. Axial energy distributions are measured with electric cut-off method. Transverse component of energy is determined from the effect of additionally introduced magnetic field on the cut-off curves. The developed set-up was tested with 60 keV, 1-10 A/cm2, 100 μs electron beam from a thermionic cathode. Analyzer performance was found to comply with digital simulation results and design parameters.
