What is AC2O?

Atmospheric Cloud Chamber of the Okanagan is a team of five undergraduate students from the Okanagan campus of the University of British Columbia. In December 2019 we participated in the Canadian Stratospheric Balloon Experiment Design Challenge (CAN-SBX) (organized by Students for the Exploration and Development of Space (SEDS Canada)) and we proposed an experiment to detect particles that originate from the decay of cosmic rays as they travel through the atmosphere.

Our experiment​

Cosmic Ray Detection through the Atmosphere. We will build a cloud chamber to detect the flux of muons and pions at different heights through the atmosphere. We aim to demonstrate the relativistic effects on muons, find the height at which pions are generated and check if the height at which these decay into muons has changed due to pollution.

COSMIC RAYS

Cosmic rays are high-energy radiation, mainly originating outside the Solar System and even from distant galaxies. Upon impact with the Earth's atmosphere, cosmic rays can produce showers of secondary particles that sometimes reach the surface.

PIONS

Pions are a type of subatomic particle consisting of a quark and an antiquark and are, therefore, mesons. They are the lightest mesons and very unstable.

MUONS

The muon is an elementary particle similar to the electron, with an electric charge of −1 e and a spin of 1/2, but with a much greater mass. It is classified as a lepton.

CLOUD CHAMBERS

 A cloud chamber is a particle detector which consists of a supersaturated vapour. When energetic charged particles interact with the gaseous mixture by knocking electrons off gas molecules via electrostatic collisions, a trail of ionized gas which follows the particle's path can be seen.
