• Resumen

  • The Wilson cloud chamber is an apparatus used for detecting and observing the trails of alpha/beta rays or even cosmic rays in saturated gas conditions. The principle of this device is based upon the powerful ionization of the aforementioned rays within the medium. This article will provide instruction for creating a classic version of the cloud chamber using a glass food container and dry ice. Some common malfunctions and disadvantages of the classic version will be discussed. Moreover, this article will introduce an improvement of the cloud chamber using the Peltier chip as an alternative for dry ice, and also compare the pros and cons of these two methods.
