Experiments

Product Information:

The Ne Franck-Hertz tube can be operated at room temperature. The tube is a tetrode featuring an indirectly heated barium oxide cathode, a mesh-type control grid, a mesh-type anode grid, and a collector electrode. These four electrodes are arranged in a plane-parallel configuration.
The connection sockets for the heater, control grid, and anode grid voltages are located on the base of the instrument. The collector current is taken off through the BNC socket at the top end of the shielding cylinder. An internal 10 kΩ limiting resistor is permanently installed between the connection sockets for the accelerator voltage (control grid) and the anode voltage. This protects the tube in the event of a spark discharge caused by the application of excessively high voltage. The voltage drop across this resistor during measurements is negligible, as the anode current in the tube is less than 5 pA. (Thus, the voltage drop across the protective resistor is 0.05 V.)
