Labs at night

Images of what some labs look like when nobody is around. I’m a little surprised at the SLAC control room picture; I would have thought they would be manned 24/7 when they were running, so perhaps this is “at night while not running.” Many optics/atomic physics labs look pretty much the same, since you often do your work with the lights out (it’s a relatively recent development that the systems I’m working on have been made “light tight” so that we don’t have to stumble around in the dark)
