Abstract

1323900 Cathode ray tubes; travelling wave tubes MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 17 Sept 1970 [19 Sept 1969] 44383/70 Heading H1D In a deflection means for a c.r.t. the method of maintaining constant throughout its length, the impedance of a helically wound slow wave electrostatic deflection structure for establishing a travelling wave field adjacent an electron beam passing through a cylindrical conductor, in which the capacitance of the structure decreases progressively in the direction of motion of the electrons due to the divergence of the passageway for the electrons, comprising decreasing the inductance of the structure progressively as the capacitance decreases e.g. by progressive decrease in the internal bore diameter of the helix. Widening of the beam passage allows increased scanning area, variations in the characteristic impedance and phase velocity characteristic being progressively compensated, and a uniform deflection sensitivity up to the order of a thousand megahertz is instanced. In Fig. 1, structure 11 is tapered at an angle # and the axis of the undefleoted beam tilted at #/2. In Fig. 2 (not shown) the beam is further deflected horizontally by deflectors 15, over display screen 16. Input coaxial plug 10a is shown. Fig. 3 (not shown) illustrates VSWR v. frequency, the VSWR value being < 2 for most of the range for input frequencies less than about 6000 MHz. Reference is made to observation of single pulse waveforms of ultra-high frequency and ultra-fast waveforms with ultrawide band frequency components.
