Finally all our Phase-I ALTO detectors are taking data. The second muon detector needs still to be filled with additional scintillator liquid, and we will do this soon.
The Phase-I of the ALTO prototype consists in the operation of two full ALTO units (two water tanks and two muon detectors). We also have other scintillation channels, which help us to understand better the behaviour of our ALTO units and to calibrate the signals.
Now thinking already about Phase-II. 🙂
