Click on the image to view a detailed photograph of the ExB tube wiring.

An electron beam grazes the back side of a phosphor coated screen within the tube. External helmholtz coils and internal capacitor plates make it possible to show magnetic and electrostatic deflection of the beam.

This demo requires our video projection equipment for large class viewing.

This demo can be found in cabinet F on shelf 1 of the UCSD PUL Demo Room (WLH 2015).
