The enclosed article has been published in the "Cathode Press" Magazine of The Machlett Laboratories, Inc.
Machlett had been a very important partner for Comet, being licensor of Comet AG for the manufacture of X-ray
tubes since the early fifties and being licensor of COMET TECHNIK for the manufacture of vacuum capacitors
since 1965. This close cooperation between COMET and Machlett came to a halt in 1989 when Machlett was
purchased by Eimac. Machlett stopped production of vacuum capacitors in 1969.
Although this article was published about 30 years ago, it is still correct in almost every aspect, except maybe
for some brand names which have been changed in the meantime. It gives a concise summary of the subject
and is interesting to read. The credit for this goes to Lars Giers who wrote the article back in 1966 as a development engineer responsible for variable vacuum capacitors at Machlett.
Lars has been our U.S. representative for vacuum capacitors and industrial X-ray tubes and is operating a successful reloading operation using Comet medical X-ray tubes.
