    摘要： A tunable RF power source is connected to a particle deflecting structure comprising a waveguide mounted to pass a particle beam therethrough and lined with a dielectric material for reducing the phase velocity of electromagnetic waves within the waveguide. The frequency of the RF source is tuned so that the phase velocity of the electromagnetic waves propagating in the waveguide equals the velocity of desired particles in the particle beam. During passage of the particle beam through the waveguide the electromagnetic waves continuously interact with the beam, but only the desired particles receive a net deflection relative to the other particles in the beam.

    摘要： Various embodiments of a helical coil deflection structure of a CRT are described and illustrated which provide shielding between adjacent turns of the coil on either three or four sides of each turn in the coil. Threaded members formed with either male or female threads and having the same pitch as the deflection coil are utilized for shielding the deflection coil with each turn of the helical coil placed between adjacent threads which act to shield each coil turn from adjacent turns and to confine the field generated by the coil to prevent or inhibit cross-coupling between adjacent turns of the coil to thereby prevent generation of fast fields which might otherwise deflect the beam out of time synchronization with the electron beam pulse.

    摘要： A device for deflecting an electron beam emitted from an electron gun in a cathode-ray tube, the device being of the type having a helical strip slow-wave structure, wherein the improvement resides in enlarging the passage of the electron beam toward the display screen of the cathode-ray tube with the characteristic impedance of the slow-wave structure maintained constant throughout the length of the slow-wave structure.
