OK, I know you all want to go get one...
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)
