k1-15

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.
