High-voltage plasma generator

laboratory

The gas discharge plasma experimental instrument is a teaching and laboratory unit that uses high voltage to produce a glow discharge in a low-pressure gas, enabling observation and analysis of plasma phenomena. It is intended for classroom demonstrations and controlled laboratory experiments to study discharge behavior, plasma luminescence and related spectra by adjusting voltage and gas pressure.

Instrument Composition:

• The instrument includes a Curie temperature tester and a mechanical assembly.
• The mechanical assembly comprises a heating device, temperature control and measurement systems, magnetization and detection units, and air cooling devices.

Product Features

• Integrated design to minimize external wiring and simplify setup.
• Discharge tube housed in an insulating enclosure to improve operator safety.

Experimental Details

• Employs the dual-probe method to measure probe volt-ampere characteristic curves across different discharge voltages.

Experimental Objectives

• Understand plasma generation mechanisms and the physical meaning of key parameters.
• Use the dual-probe method to determine electron temperature and electron density of a gas discharge plasma.

Technical specifications:

• High voltage: 0–2000 V, continuously adjustable.
• Probe voltage: 0–170 V, continuously adjustable.
