PCT No. PCT/SE96/00289 Sec. 371 Date Dec. 12, 1997 Sec. 102(e) Date Dec. 12, 1997 PCT Filed Mar. 5, 1996 PCT Pub. No. WO96/28887 PCT Pub. Date Sep. 19, 1996A device for generation of electric square pulses with a short rise time, comprises at least an energy-storing capacitor in the form of a coaxial cable with an insulated screen, wherein essentially the whole coaxial cable is wound up in an inner closed cylindrical container of metal, a direct-voltage source for charging this screen, and devices for short-circuiting the screen to zero potential during generation of pulses. These devices together with the inner cylindrical metal container are enclosed in an outer closed container of metal, and one end of the coaxial cable is intended for connection to a load and the other end of the coaxial cable terminates with a resistor which has the characteristic impedance of the cable. Between the inner cylindrical container and the outer container, a ferrite ring-core is placed around the devices for short-circuiting and both cable ends.
