Franck-Hertz Mercury tube with Oven
Franck-Hertz Mercury tube with Oven
TEL-8482550-115-2
Free electrons colliding with mercury atoms emit energy in quantized packet. The excitation energy at 4.9 eV can be determined. A highly-evacuated cathode ray tube with mercury gas filling and plane-parallel electrodes to avoid distortion of the field lines. Electrodes include an indirectly heated, oxide cathode, perforated to produce a homogenous electric field plus an anode grid and collector (counter) electrode. To raise the probability of collisions between electrons and mercury atoms to a sufficient amount, the tube needs to be heated using a special heater. This heater is used for adjusting the vapor pressure in the mercury filed tube. It is a spray-painted metal housing with the tube symbols printed on the front panel that are visible from a distance, ceramically insulated connection sockets, viewing windows, opening with spring clamp for thermometer in the lid, insulated carrying handle and built-in thermostat for adjusting temperature.
