Solving a Disappearing Voltage Puzzle: The Ball Cyclotron Project

Click For Summary
SUMMARY

The discussion focuses on troubleshooting voltage loss in a ball cyclotron project utilizing a Van der Graaf generator. Users identified that the charge may dissipate into the air due to environmental factors, particularly humidity. Recommendations include avoiding sharp points on connecting wires, using alligator clips, and ensuring clean surfaces to prevent leakage. Additionally, increasing the distance between oppositely charged strips may help maintain voltage levels.

PREREQUISITES
  • Understanding of electrostatic principles
  • Familiarity with Van der Graaf generators
  • Knowledge of static electricity behavior

Homework Statement


I'm making a ball cyclotron (https://rimstar.org/science_electronics_projects/ball_cyclotron_electrostatic_accelerator.htm) for a school project. To generate enough voltage, I'm using a Van der Graaf-generator. The problem is that all the voltage, which I can measure, suddenly dissapears when I connect the generator with the alumium tape.

How is this possible and how can I solve this?

The Attempt at a Solution



My tutors think that the charge dissipates into the air.
 
Physics news on Phys.org
Static electricity has a way of dissipating.
Try to avoid any sharp points (pointed ends of connecting wires, etc.)
Alligator clips should work OK.
You might try folding the edges of the foil strips to get rid of the sharp edges.
Also, the bowl would have to be clean to prevent leakage between the strips.
Maybe the distance between the oppositely charged strips could be increased.
I built a "Kelvin Water Dropper" (Kelvin's thunderstorm) and once noticed that
it didn't seem to work as well in high humidity.
