Frequency-Dependent Distortions of Pulses in the Traveling-Wave Cathode-Ray Tubes

Abstract

Helical and meander slow-wave structures are used for deflection of the electron beam in the traveling-wave cathode-ray tubes for the super-wide-band electronic oscilloscopes. The deflecting electromagnetic field in the systems has surface character. For this reason the frequency-dependent distortions of signals arise during the deflection of the beam. The transient responses of the tubes are considered in order to reveal opportunities to reduce frequency-dependent distortions.
