Some EMC aspects of a 2 MV Marx generator:with sensitive diagnostic equipment in the immedeate vicinity

A 2 MV lightning surge generator is a powerful source of interference, in particular when the voltage waveform is chopped by a shorting spark gap. We not only do need to protect the sensitive diagnostic electronic equipment that operates on small signals, but we also should guarantee its flawless operation during the discharge. The paper discusses the setup, the EMC measures taken, and the results of verification measurements. Some typical results obtained in the research with this instrument will be shown as well.
