Development of vacuum capacitors

Vacuum capacitors are particularly suitable for high-frequency high-voltage operation in airborne radio equipment. Capacitors developed to fulfil requirements of a specific nature revealed a number of interesting effects which are explained qualitatively, and which have considerable influence on the capacitor design. The results are of general application and tests on the capacitors developed show that their performance is very satisfactory. It is believed that, for the requirements specified, no other type of capacitor has a comparable performance.
