It's Bob Tjoelker in front of the Deep Space Atomic Clock (DSAC) being 
tested for magnetic field sensitivity.  It's a trapped ion clock, 1 
liter/1 kg, orders and orders of magnitude better than a USO in performance.

(if it's in the building I think it's in, the rebar is made of 
non-magnetic stainless steel)
