11. By this time, cloud chamber observations had clarified the nature of the hard component. 12. "Cloud Chamber " by Michael Dorris ( Scribner, $ 12) 13. Rossi's group focused on the use of cloud chambers to study their properties and interactions. 14. The same principle can be used to extract information in experiments involving the cloud chamber . 15. Also in 1938, Maier-Leibniz built a Wilson cloud chamber . 16. Depending on what you are trying to measure, you could go'old-school'and make a'cloud chamber '. 17. This project also constructed a sensitive high-pressure diffusion cloud chamber as the cyclotron's main detector. 18. This added another way to use cloud chambers to measure the properties of elementary particles. 19. The bubble chamber is similar to a cloud chamber , both in application and in basic principle. 20. His research employed a Wilson cloud chamber and focused on the problem of the long-range alpha particles.
