Product Overview

The Wilson Cloud Chamber is a classic demonstration apparatus for visualizing the paths of alpha particles. It operates by saturating air with alcohol vapor and using a hand-operated vacuum pump to create a partial vacuum. This causes supersaturation of the vapor, enabling ionized particle paths to become visible as fine condensation trails.

When an alpha-emitting pin source is inserted into the chamber, the emitted particles ionize the surrounding air. Alcohol vapor condenses along these ionized tracks, forming tiny foggy streaks—direct evidence of atomic particles in motion.

Key Features:

  • Classic wet-type design using alcohol vapor and vacuum-based supersaturation

  • Clear visibility of alpha particle tracks using an external light source (not included)

  • Simple, portable setup for classroom demonstrations of radiation and ionization

Kit Contents:

  • Base assembly with sealed chamber and clamping screws

  • Rod to insert an alpha pin source through the side of the cell

  • Hand-operated “one-pull” vacuum pump with flexible hose

  • Squeeze bottle for handling radioactive powder, with chamois filter disc, tubing, and Mohr clip

  • Support rod with knurled fixing screw, allowing the chamber to be elevated for better viewing

Specifications:

  • Dimensions: 120 × 110 × 65 mm; 4.7 × 4.3 × 2.6 in

  • Weight: 0.34 kg; 0.75 lb

  • Designed and manufactured in Australia

Note: Alpha radioactive sources and illumination lamp (e.g., LED torch) are not included. A clamp or holder may be used to position a torch to illuminate the interior from the side.
