 .:: Ball Lightning / Plasma Generation ::.
|
Purpose:
The purpose of this experiment is to create ball lighting via microwave stimulated plasma and observe its behavior in the elecromagnetic field.
Materials:
- Basic 2.458GHz resonant cavity (w/ 1kW magnetron)
- Small flame (peice of lit paper)
- Plate or non flamable surface (to protect the base of the microwave cavity)
Procedure:
- Place small flame on a plate
- Place the plate inside the microwave cavity (oven)
- Activate the magnetron
- Turn off after a few seconds of ball lightning to avoid dammage to cavity

This clip shows plasma being stimulated by microwave (2.45GHz) and then with carbon in the system.
Results:
After analyzing these sequences the following conclusions and approximations can be made.
- Plasma ball rises about 100mS after formation (after the first formation)
- Plasma balls can be maintained for up to about 300mS
- Plasma balls can remain in flight for up to about 200mS
- Plasma ball diameter can reach about 10cm
- Plasma rise velocity reaches a maximum of about 1.5m/s to 2.0m/s (in still air)
- If a small plasma ball begins to rise another one often follows it because of the remaining power which is enough to support another small plasma ball
