Tube holder to support all S series (student) electron tubes for easy and safe operation. The five pin sockets for the tube are concealed inside the tube holder. A cathode protection switch is integrated into the tube holder, to protect the heated cathode from excessive voltage.
Control unit for operating the critical potential tubes. Equipped with an output for sawtooth acceleration voltages; adjustable upper and lower limits of the acceleration voltage. Integrated pico-ammeter amplifier for anode current measurement.
Teltron Critical Potentials Tube S with He-Filling for quantitative investigations of inelastic collisions of electrons with inert gas atoms. Cathode filament voltage: UF </= 7V; Anode voltage: UA </= 60V; Anode current: IA </= 10 mA
Cover, Material: Rugged ABS plastic, For E/M Apparatus, Protects the bulb of the e/M Apparatus during transport, Provides viewing of the e/M Apparatus in lit classrooms
Highly evacuated electron tube with focusing electron gun and fluorescent screen inclined relative to the beam axis, so that the path of the beam can be seen and the effects of electric and magnetic fields can be studied.
