The large DAQ bunker would definitely be the better option if you can manage it.</div>

I wonder if the additional radiation is an issue. The expansion module has lost contact twice now and I am trying to see if there is something to it concerning radiation or perhaps just a network issue.</div>

I know you are planning to move the shielding bunker and that will move the power supplies and interface chassis. My current plan is install the controls in that shielding. But I am wondering if using the larger bunker (DAq I think) for the controls IO connections
may be a better option.</div>

We are getting quotes in for the thermocouple extensions now and I am using 100' as a length. Can someone calculate the run from the detector to the large bunker? Just for the controls, so it would be the thermocouple extensions (~200 pairs) from the detector,
and then some low voltage runs from the controls to the power supplies (control voltage = 16 pairs, current readback = 16 pairs).</div>

I'll keep an eye on the system this weekend and see if the issue persists.</div>

Just going from memory, I think it is IBC1H04CRCUR2. The current is lower but the radiation is higher because now we have a liquid target as opposed to gas before.</div>

Do you guys know the PV name for the beam current in Hall A? Also, in general, is the beam current higher now than in November?</div>
