This portion of a cosmic ray shower was recorded in a Supersaturated Environments Cloud Chamber located near sea level. Note the group of parallel tracks. It is possible to observe several such events per hour with our lecture hall and museum cloud chambers, and record them on videotape.

These low energy cosmic rays were recorded in a Supersaturated Environments Cloud Chamber. Trajectories were bent by the 1000 Gauss magnetic field produced by our rare earth magnet, which was placed just below the central fiducial mark. Note the increase in curvature and ionization per unit length as the lower energy particle is slowed.
