You can find the plasma laboratory in the big hall inside the courtyard of the physics department. Get to the big gate with glass windows – you will be looking into the machine workhop and the lab is also there. At the right side of the gate there is a bell, ring it and a bearded figure will come out of the lab to welcome you. In case of difficulties just go round the corner to the office “Servizi generali” (general services) and ask for Giancarlo Maero.
