Demo Number	412
Location	Shelf On a cart by the main door
Description	Creates electron beam that can be moved by the voltage in the Helmholtz coils.
Related Demos	034, 413, 402
Tips	Procedure: Plugin both power supplies. It will take a couple of minutes to get a beam. Once the beam is visible (will probably need the lights off), turn on the smaller power supply. You can adjust the voltage on the smaller PS to change the trajectory. This demo shows how old CRT TVs work.
