Subatomic particles are far too tiny to see. The Bubble Chamber is one way to visualize the tracks left by these particles. The tracks are made visible as a trail of bubbles in a superheated liquid that is about to boil. For a more detailed explaination please see the CERN web page.
This Java-script program simulates events in a Bubble Chamber. It will simulate one particle,
the decay K- + p→Λ π+ π- (Λ→pπ-),
and a Higgs decay in a Collider experiment (See Properties, under File). It also allows changes to the momentum and
magnetic field, as well as track identification and momentum calculation.
It downloads in a zip file. To start the simulation either Double-Click on the file "Bubble1.1.jar" or from within that
directory type "java -jar Bubble1.1.jar". It needs Java 5 (JRE 1.5) or greater. The Current version is 1.1.
