Explanations for the Animation „Alpha Particles in Crossed Fields“
This animation provides insights into the properties of alpha particles, including their behavior in air, vacuum, or crossed fields. Through a virtual experiment, the animation demonstrates how to determine the natural velocity of alpha particles. The animation allows for step-by-step progression, based on the settings selected via the SETTINGS button.
The virtual experiment involves the following setup:
- Vacuum pump
- Chamber with a sample and capacitor plates
- Alpha particle sample Am 241
- Capacitor plates with a distance d=0.9 mmd = 0.9 \, \text{mm} and a fixed voltage U=3000 VU = 3000 \, \text{V} (electric field)
- External magnetic field, continuously adjustable, perpendicular to the electric field
- Aperture with a small window 3.5 mm3.5 \, \text{mm}
- Geiger counter
