Wilson’s cloud chamber

Description

SP4-2029
Wilson’s Cloud Chamber is the classical pattern where
alcohol saturates a pad in the chamber and a vacuum pump
(reversed tyre pump) is used to draw a partial vacuum to
super saturate the remaining air with alcohol vapour.
An Alpha ‘pin source’ in the chamber emanates particles
that ionise the air particles along the path. The alcohol
vapour condenses on these ionised paths to display
miniature foggy tracks inside the chamber. These tracks
indicate the path the Alpha particles took.
A light source is required (microscope lamp) to illuminate
the cell and a ‘pin source’ of Alpha material is required.
it is intended at a later date to redesign this item again to
modernise and to reduce the cost.
