Thermoelectric Cloud Chamber

The Thermoelectric Cloud Chamber is the perfect alternative to existing time-consuming dry ice variants. The chamber is self-contained and thermoelectrically cooled. It requires no dry ice or water; the only setup necessary is the addition of isopropyl alcohol and connection to an outlet. The chamber contains an integrated power supply and illumination of the chamber is provided by a high-intensity LED. Using the provided source, ionizing radiation tracks should be visible within 10 minutes. Once running the cloud chamber can be made to run for extended periods by adding more alcohol through the access provided in the lid. The source provided is a thoriated tungsten rod (2%). Thorium is an Alpha emitter and the primary tracks will be due to alpha particles. Occasionally Beta tracks will be seen due to the daughter nuclei of previous decays.
