Tube Type: High-vacuum diode tube (historically a Crookes or Braun tube variant).
Screen: Flat or slightly curved faceplate coated internally with a cathodoluminescent phosphor (often zinc sulfide, emitting a green glow).
Operating Voltage: Requires a High-Voltage Power Supply providing 1,000 V to 5,000 V for acceleration (anode) and a low voltage for the filament (cathode heating).
Electrodes: Includes a heated filament/cathode, an anode, and typically additional control/focus electrodes.
Compatibility: Designed for use with external Deflection Coils or High-Voltage CRT Power Supply.
Clear Fluorescence: Features a phosphor-coated screen that generates a bright, visible spot or trace when struck by the electron beam, clearly demonstrating the conversion of kinetic energy into light.
Electron Deflection Study: Designed to be used with external electric or magnetic deflection coils (not included) to show the effect of fields on the electron beam, confirming the negative charge of the cathode rays.
High Vacuum Build: Constructed from robust, thick-walled glass to maintain a high internal vacuum, which is necessary to prevent electron scattering and ensure a straight, focused beam path.
Fundamental Physics: An indispensable educational tool for illustrating key historical experiments by figures like J. J. Thomson and for explaining the fundamental structure of matter and electricity
Safe Operation: Equipped with internal components and robust connection points for reliable and safe use with a dedicated high-voltage power supply.
