A Rogowskl coil has been used to measure current in a pulsed discharge circuit. The frequency response of the coil has been determined experimentally,
It has been established that the noise signal associated with the measurement of a pulsed discharge current is due principally to the electromagnetic radiation from the spark gap switches required in such a circuit. The radiation can be reduced by pressurizing the spark gap with argon, but at the same time the breakdown potential of the switch becomes erratic.
A simple measuring system has been devised which completely eliminates the noise signal from the current waveform. The system consists of a balanced differential preamplifier which is fed by a completely balanced measuring circuit into which a 0.5ยต sec delay line has been incorporated. / Science, Faculty of / Physics and Astronomy, Department of / Graduate
