See some ALTO events in this video!


Here are some events seen in the prototype setup at Linnaeus University in Växjö. Thanks to Jean-Pierre we have a super event display!

We are still waiting for the final scintillator detectors, and as you may see, one Cherenkov tank is not active, as we need to replace the photomultiplier.

Most of the events are atmospheric muons, i.e. muons created in the atmosphere by the collisions of protons with the atomic nuclei composing the air.

On the right-hand side, one can see the detected charge given in millivolt as a function of time and each colour corresponds to one detection channel.

The size of the spheres corresponds to the magnitude of the signal seen in each detector.

Have fun!
