[Halld-tagger] request for patch panel from collimator cave

[Richard Jones]

Hi Fernando,

I don't know where this request should be routed, so I am sending it directly to you.  I would like to make sure that we have coaxial connections from the upstream wall of the collimator cave to the counting house.  Here are some signals that we would like to be able to read directly, and minimize how much DAq electronics we need to place in a hot radiation area.

 1. output signals from the active collimator: 8
 2. cave background rate monitor scintillators: 2-4

A panel of 16 or 24 would be sufficient, I believe.  There are also controls for the collimator translation stage and associated limit switches.  Further downstream there is the converter target ladder, which may be inside the cave or outside, depending on the ability to shield the stray magnetic field from the pair spectrometer.  I just want to make sure we have cables and cable trays for these interconnects, as it may be difficult to add them later.
