The video clip How William Shatner Changed the World - Dr. Marc D. Rayman, Chief Propulsion Engineer, NASA, JPL contains several shots of what looks like an ion propulsion laboratory at JPL. The video was uploaded in 2009 and the lab may be older than that (Deep Space 1 was launched on 24 October 1998).

Below are several screen shots of the lab, including two prominent features:

1. a large circular pattern with what looks like about ten mass flow controllers for input gasses and a few controllers for pumping ports and a big analog mechanical needle gauge reading pressure perhaps
2. a large hexagonal arrangement of 37 rectangular control panels

Question: What JPL laboratory is this exactly, and what are the functions of these amazing-looking control panels?
