Electric Deflection of Electron Beam
From UO Physics Demonstration Catalog
Return to Electric Fields and Potential
Description:
The beam from an electron gun can be deflected by the field of two parallel plates. The beam is intercepted by an angled phosphorous coated screen (with grid) which glows to show the path of the beam. Beam can be bent with a bar magnet displaying Right Hand Rule. Beam can also be bent with an Eletric field by connecting the deflection plates in parallel with the accelerating High Voltage Power Supply, or by using a second High Voltage Power Supply,
