21. Valhalla was sketched by a series of skewed white lines that looked like tracks through a cloud chamber . 22. It began in New York, a harbor crisscrossed by wakes like particle trails in a Wilson cloud chamber . 23. Second one appears to be a likeness of a cloud chamber , compare e . g . image here. 24. During the decade from 1950 to 1960, Ney's cosmic ray research shifted away from cloud chambers toward emulsions. 25. :The second one is an image from a bubble chamber ( a cousin of the cloud chamber ). 26. Much higher degrees of supersaturation are possible in clean air, and are the basis of the cloud chamber . 27. DiMaggio and the ball might as well have been the paths of two mesons colliding in a cloud chamber . 28. He did important work in the development of high-pressure cloud chambers for the study of neutrons produced by accelerators. 29. A fourth method involves the use of cloud chambers to detect the secondary muons created when a pion decays. 30. Charles Thomson Rees Wilson was inspired to invent the cloud chamber after a period spent working at the observatory.
