Abstract

The present invention relates to an apparatus for generating high-voltage pulses, in particular by means of an inductive coltage adder (IVA), wherein an inner conductor (1) of a coaxial transmission line (21) is in the form of a body which is rotationally symmetrical to a main axis (HA) of wave propogation and passes through all stages, the outer radius of said body being formed so as to decrease in size continuously from the first to the last stage with a constant pitch.

First claim

1 - 14 . (canceled)

15 . An apparatus for generating high-voltage pulses, comprising:
an inductive voltage adder, including a transformer having voltage sources arranged along a wave propagation main axis in a series circuit with discrete stages, each stage including a radial transmission line and a coaxial transmission line, whereby waves respectively propagate along the radial transmission line into the coaxial transmission line during the pulse generation producing a combination of electromagnetic fields, the inner conductor of the coaxial transmission line, formed as a body rotationally symmetrical with respect to the wave propagation main axis and passing through all of the discrete stages, having an outer radius decreasing continuously with a constant slope from a first stage to a last stage.

16 . The apparatus as claimed in claim 15 , wherein the inner conductor has an external geometric shape of at least a portion of a straight cone.

17 . The apparatus as claimed in claim 15 , wherein the inner conductor has a conical shape.

18 . The apparatus as claimed in claim 15 , wherein the outer conductor of the coaxial transmission line is a hollow body, rotationally symmetrical with respect to the wave propagation main axis provided discretely in each stage, having identical inner radii and identical outer radii in each stage.

19 . The apparatus as claimed in claim 18 , wherein the hollow body in each stage is a hollow cylinder.

20 . The apparatus as claimed in claim 15 , wherein the radial and coaxial transmission lines are constructed of an identical material selected from the group consisting of copper, steel and aluminum.

21 . The apparatus as claimed in claim 15 , further comprising electrical interconnections between the discrete stages having a modular design identical for all of the discrete stages.

22 . A method for generating high-voltage pulses in an inductive voltage adder, comprising:
combining, during pulse generation, electromagnetic fields from a series circuit of discrete stages, arranged along a wave propagation main axis, of voltage sources in a transformer; and respectively propagating waves along a radial transmission line into a coaxial transmission line in each stage, the inner conductor of the coaxial transmission line, formed as a body rotationally symmetrical with respect to the wave propagation main axis and passing through all of the discrete stages, having an outer radius decreasing continuously with a constant slope from a first stage to a last stage.

23 . The method as claimed in claim 22 , wherein the inner conductor has an external geometric shape of at least a portion of a straight cone.

24 . The method as claimed in claim 22 , wherein the inner conductor has a conical shape.

25 . The method as claimed in claim 22 , wherein the outer conductor of the coaxial transmission line is a hollow body, rotationally symmetrical with respect to the wave propagation main axis provided discretely in each stage, having identical inner radii and identical outer radii in each stage.

26 . The method as claimed in claim 25 , wherein the hollow body in each stage is a hollow cylinder.

27 . The method as claimed in claim 22 , wherein the radial and coaxial transmission lines are constructed of an identical material selected from the group consisting of copper, steel and aluminum.

28 . The method as claimed in claim 22 , wherein all of the discreet stages have a like modular design in respect to electrical interconnections between adjacent stages.
