Very nice. What is the name of the device that everyone has their arms on?

It's the set dressing for Quinn's sliding machine in the basement lab. The set dressings included the sliding coils and these sliding towers. In my personal head canon, the sliding coils are for harnessing exotic matter to trigger an opening in the gateway and the towers are for isolating a vibrational frequency to secure an exit point. I assume that as an anti-gravity machine, the exotic matter was originally to trigger particle repulsion to achieve lift and the towers were for controlling direction.
