Tim’s Wilson Cloud Chamber

Tim’s Wilson Cloud Chamber

Author: Tim

These are a few photos from a pulsed-style Wilson cloud chamber. Unlike the frustrating-to-get-working dry-ice continuous cloud chambers, this worked right out of the gate. A rapid decrease in pressure instantly reveal these alpha and beta tracks. These are just a few of the hundreds to images I have taken with this system.

The thin tracks are from beta particle and the thicker one alpha particles.
Radium watch dial hand as the source.
Sideways illumination
The thin skinny tracks are beta particles.
Here is a photo that must have been pair production, note two opposing skinny tracks.
