Subject: rack & cable routing reorganized 

 [Alastair, Zach]

As planned, we have reorganized the instrument placement and signal routing to be cleaner and more efficient. The general structure is to have nearly all of the instruments (FGs, servos, supplies, filters, etc) in the rack under the monitors, with one BNC patch bay dedicated to carrying signals to and from the experiment. A separate bay provides access to the DAQ from the rack for acquisition/excitation. A single cable runs from the DAQ to the experiment to provide the slow control for the laser. We opted to have the AOM amplifier on the table to minimize the distance the ~6W of electrical power has to travel to the modulator.

Four channels between the table and the rack are dedicated "scope" channels; this way, we can have any of rack-bound signals viewable on the scope at the table while futzing with the experiment. 

As you can see, this already leaves a lot of space on the enclosure shelf for anything we may HAVE to put there in the future. The power supplies visible in the picture will also be moved elsewhere.

Also, we checked an unused Marconi out of the 40m so that we have one for each the AOM and the PLL. I think we were supposed to do this a while ago.
