Team at CSA
We are sending up a cloud chamber on a stratospheric balloon to detect cosmic rays.
Our undergraduate team is from the Okanagan campus of the University of British Columbia.
Cosmic Ray Showers (Source: NASA)
Cosmic rays are high-energy particles originating from the Sun and outside the solar system. Upon impact with the Earth's atmosphere, they produce showers of secondary particles.
The cosmic rays we are interested in:
Electrons, Positrons, Protons, Alpha particles, Muons, Pions.
First cloud chamber
A cloud chamber uses supersaturated vapour to detect particles. Energetic charged particles interact with the gaseous mixture by knocking electrons off gas molecules via electrostatic collisions, this produces a trail of ionized gas which follows the particle's path.
