Hi All,
The monster vdg pair which the boston sci museum has used to be used
as a particle accellerator. Each sphere was 4MV either + or - and an 8MeV
accellerator was strung between them. In each sphere there were scientists
operating the accellerator.
The filament, instruments cloud chamber magnets etc. were powered by large
batteries to get around having to put power feeds up to the spheres.
