"Hg Jones" tubes...
Frank hand carrying Mercury tubes from
Lutz Neumann's factory to the USA
Replica Morgan high vacuum tube with mercury vapour - the arc
appears greenish, though the vacuum is a Crookes vacuum
Must wonder though if in the original experiment it was the glass itself
that was green (ie, X-Rays??)
Man in a Crookes Tube!
4 Triboluminescent tubes, 3 with neon and one high vacuum. Cool!
