This tube is only suitable for use with the control unit 1008506!
Hertz electron tube for quantitative investigations of inelastic collisions of electrons with inert gas atoms, determination of ionization energies of helium, as well as resolution of the energy states of various primary and orbital angular-momentum quantum numbers. Includes shielding and battery unit for the collector voltage (battery not included).
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. Allows recording of the acceleration voltage as a function of the anode current. A slow sawtooth voltage (approx. 6 seconds per cycle) is available with an interface or XY-recorder; a sawtooth voltage with a repetition rate of 20 Hz is available for oscilloscopic observations.
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. The base plate has a slot for attaching the studentsí Helmholtz coil pair 1000611 (U185051).
