Today we received the first muon detector that we will fill with a liquid called "scintillator" next week. Next week we will also install the photomultiplier which will record the photons emitted by the passage of particles in the scintillator liquid.
Here some pictures from the delivery and installation, and a video from today, where we had not the best weather possible :)
Arrival of the aluminium tank at the ALTO prototype site can be seen in the following picture:
It was quite an easy installation of the muon detector, as it rolls on wheels:
And finally this picture shows the muon detector installed below the concrete layer at the ALTO prototype site.
