Thank you for the great explanation to you and your coworker! The documentation by Oxford Instruments and the tour are really cool. As far as I understand, almost the entire construction is a kind of a cooler. The actual quantum processor is located at the bottom of the upside-down pyramid. To make it work properly, the construction should be loaded through a ceiling to a special room with no air. It takes around 24 hours to meet working conditions.
I'm still trying to guess what the rings on pipes are standing for? [1]
