Details

Maltese Cross style Cathode Ray Tube for use in demonstrating that electrons in a Crookes tube travel in straight lines and are affected by magnetic fields.

The glass itself is in pristine condition, with no scratches or cracks visible. The Maltese Cross sits on a black Bakelite stand that can be removed. The metal connectors show very little signs of corrosion.

The cross inside the tube is hinged, so it could fold down against the floor of the tube. When the tube is turned on with the cross up, it casts a sharp cross-shaped shadow on the fluorescence on the back face of the tube, showing that the electrons move in a straight line. After a while the fluorescence would get 'tired' and decrease. If the cross was folded down out of the path of the rays, it no longer cast a shadow, and the previously shadowed area would fluoresce stronger than the area around it.
