- establishment of the cathode ray gun (diode electron gun)
- excitation of luminescence by ultraviolet light.
- excitation without ionization, no charge emitted
- persistence and infrared quenching
- The metastable state of excitation
- Different colors, analysis spectroscope
- Introduction of concept of excitation potentials
The diode gun, a tungsten wire “hairpin” filament and a cylindrical anode, projects a wide beam of cathode rays into the experimental zone. This beam is intercepted by the phosphor screens. All connections are made on the Universal Stand.
Anode voltage, 2000-5000V, DC
Maximum filament voltage, 7.5V.
Anode current at 4000V, 150µA.
