Condition :	Good
Principle :	Electron Beams
Area of Study :	Modern Physics
Equipment :	Break apart and Demo X-Ray Tubes, X-Ray Tube, X-Ray Tube Transformer, Variac, Fluorescent Screen, X-Rays (Films).
Procedure :	Directions for operating the X-Ray unit. Hook the good X-Ray tube to the transformer, and hook the transformer to a Variac. Turn the Variac to about 70 VAC or until the image on the fluorescent screen is clear. Caution: Do Not Overload, Do Not Operate for more than 30 seconds continuously. Make sure the transformer has enough oil in it. This unit is NOT legal as far as output is concerned. The films may be viewed by putting them on the overhead projector. Several large X-ray tubes are mounted on Plexiglas stands for display.
