Ionisation Potential Set-up (IP-01)
High accuracy and stability, Bench-top form factor, Designed for educational and research use.
The electrons in the atoms have discrete stationary states. Franck and Hertz in 1914 described the rst observation of quantized excitation from one quantized state to another one year after N. Bohr published his theory of hydrogen atom. His method depends on detecting the on-set of inelastic collisions between electrons and atoms of the gas under study. The experimental tube in this measurement is essentially a triode lled with the vapour of the experimental substance. The electrons emitted by the heated lament of the tube are accelerated by the positive potential VGK between the cathode and the grid. The grid is a wire mesh which allows the electrons to pass through. The anode A is maintained at a xed potential VGA slightly negative with respect to the grid.
