Info

A large diffusion cloud chamber is filled with supersaturated alcohol vapor that is cooled by liquid nitrogen. The resulting cloud forms condensation trails along the path of charged particles. The best way to “see” cosmic rays and other ionizing radiation. Includes a port for an alpha particle source. Please request several days in advance to make sure we have liquid nitrogen.

[Please allow for long setup time and request several days in advance to secure nitrogen]
