K1-15. Oscilloscope CRT - Deflection By Electric Field
Purpose
To demonstrate the deflection of an electron beam by an electric field.◙
Equipment
Oscilloscope CRT with charging materials and battery with leads.◙

Description
The electron beam starting at the rear of the tube is seen on the front fluorescent screen in the standard way. Holding a charged rod near the tube creates an electric field which deflects the beam. Connecting a battery to contacts at the back of the tube puts an electric field on two sets of internal deflection plates, causing either horizontal or vertical deflection of the beam.
