Bubble chamber pictures for the classroom

Bubble Chamber

Bubble chambers were the dominant experimental tools of particle physicists in the 1950s and 60s. They supplanted cloud chambers and lead to the Nobel Prize in Physics 1960. Bubble chambers and cloud chambers work in a very similar way. And although it is not possible to build a bubble chamber in the classroom, students can analyse bubble chamber tracks and learn more about particle identification, e.g. after having built and observed cloud chambers.

This worksheet is based on images recorded by the 2 m bubble chamber at CERN on 10 August 1972. The bubble chamber was exposed to a beam of protons from CERN’s proton synchrotron PS with a momentum of 24 GeV/c. The original pictures as well as the pictured with coloured tracks can be found online: https://cds.cern.ch/record/2307419
