This message is intended for folks interested in rf generators,
particularly those who expressed interest in the design published a
few years back by Ron Jones, Dieter Gerlich, and I. A cheaper, and
more easily constructed version of the design is just coming out in
Rev. Sci. Instrum. (vol 71 p 4335). The generator is designed to
drive ion guides and traps, but should be adaptable to any capacitive
load (e.g. rf discharges) where the power requirement is below ~140W.
The new version still has the essential features, but is smaller than
a loaf of bread, contains < $100 of parts, and can easily be
constructed by a novice. Shortly, I hope to add additional
construction information under the "Utah rf source" link on my web
page, below.
