Bubble chamber with colour enhanced tracks

This artistically-enhanced image shows the tracks of real particles produced when a neutrino interacted in a liquid mixture of neon and hydrogen inside the Big European Bubble Chamber (BEBC) during the 1960s. The tracks become visible when bubbles form along the paths of the particles as a piston expands the liquid. A magnetic field is produced in the detector causing the particles to travel in spirals, allowing charge and momentum to be measured.
