Wilson chamber

The CERN/ETH Cloud Chamber is now steadily accumulating photographs (one every five minutes during operating periods) for the study of the decay of K°2 particles. At the controls in this picture, are A. Dalluge (left) and G. Chil, while R. Pegaitaz makes an inspection below. In the foreground is the air platform which is placed underneath to 'float' the chamber during final alignment.
