Sketched design for an arrangement of laboratory equipment to produce continuous supersaturation within a cloud chamber.

The cloud chamber was a device for visualising subatomic particle tracks, using condensing water vapour within a sealed chamber. It was invented and developed by C.T.R. Wilson from 1911 and variations on the idea were widely used by particle physicists until the 1950s. This drawing, inscribed ‘December 1932’, is from a notebook kept by C.T.R. Wilson in the period 1928-1939.

Charles Thomson Rees Wilson (1869-1959) British physicist, was elected a Fellow of the Royal Society in 1900. He shared the Nobel Prize for Physics in 1927 for his work on the cloud chamber.
