Abstract

A 1 Megajoule fast condenser bank is being built at Frascati to energize a Plasma Focus experiment of large dimensions.

The condenser bank has the following characteristics: energy 1 MJ, voltage 40 kV, capacity 1250 microF, internal inductance 8 nH, number of condensers 96, repetition rate 1 shot every three minutes.

The construction of this modular condenser bank has been simplified to a large extent by using new techniques; spark-gaps built in the condensers, connection by cables with plug-in connectors, precollectors with built-in in R.C. matching elements, triggering by triax cables.

A rather unusual circuity (the spark-gaps are grounding the high voltage terminal of the condensers) eliminates the ringing of the charging and triggering elements at the frequency of the main discharge reducing the electric stress on these elements and the emission of electromagnetic noise.

The condenser bank is now completely assembled. Full energy tests are under way.
