Transmission Line of the Capacitor Cell of High Repetition Rate Discharges

Transmission lines from 15-m to 25-m long are intended to connect capacitor cells of 6 kV, 36 kJ with load. The lines shall transmit the packets of cell discharge current pulses with an amplitude up to 100 kA and with a repetition rate of 1 Hz within 20 min. The transmission line in the cell serves as an inductor which limits the discharge current, transforms the energy released at the discharge of capacitors into magnetic field energy, and then, after a crowbar diodes are switched on, transmits the magnetic field energy to the load. This article presents the transmission line design and the results of calculations and experimental study of electrical and thermal parameters of the transmission line operating in the conditions of sharp skin effect. It also describes the techniques used to align the inductances of the transmission lines with various lengths of several capacitor cells operating into the total load, the estimations of the forces acting between the line wires, and the requirements for the tightening elements of the transmission line.
