A very rich 'typical' bubble chamber picture
This is a bubble chamber picture. It contains examples of many characteristic features that need to be recognised if one is to be able to interpret such pictures.
Here, the CERN 2 metre-long bubble chamber was filled with liquid hydrogen
- a clean source of proton targets (no neutrons) - and exposed to an incoming parallel
beam of negative kaons (
) with an energy of 8.2 GeV, entering from the bottom of the picture.
All tracks that are not associated with the parallel beam are background and will be removed from subsequent pictures.
