The project

From Particle Physics to Special Relativity.
Go to Scientific Background

Scientific Background

We aim to verify that Special Relativity works for particles that travel close to the speed of light, by calculating the half-life of the muon decay.

The experiment & our detector

We will fly a Cloud Chamber on a stratospheric balloon and record the muons that get through it during the flight, to obtain the flux of muons in each range of altitude.

Go to Design & Construction

Design & Construction

Design, construction and development of a Cloud Chamber for particle detection. Especially to detect muons (elementary particles) and their traces along the chamber.

Go to Sponsors


Development of an outreach programme to bring our experiment, physics and engineering a little closer to the general public. We intend to broaden the public’s engagement and to obtain sponsorships to fund the experiment.


Cloud chamber for high Altitude Detection of Muons Under Special relativity effects.
From particle physics to special relativity

Special Relativity is a theory that has always caught our attention. Despite being based on basic mathematical transformations, its consequences are still surprising and in most of the causes they may sound as science fiction. That is why we always had in mind to experiment with it to see whether they are ultimately true or not. We are also interested in particles so we knew about the existence of a cloud chamber, a not so complicated detector that can keep track of the particles that break through the detector. Joining this two ideas we came up with our experiment: using a cloud chamber to prove Special Relativity.


Our team is formed of eager hard-working students in pursuit of new challenges and seeking to learn and discover.
