 The readout from the ion gauges in the S3 vault is available through the control system, but these gauges cannot be turned on and off remotely. They are switched on and off locally by pressing the **EMIS** button on their controllers, which are located in the S3 vault on the middle level in the electronics racks under the stairs to the top level. An ion gauge must be turned off by entering the vault before its beamline section can be vented. The readout from the ion gauges in the S3 vault is available through the control system, but these gauges cannot be turned on and off remotely.

-The ion gauge for the Object Box vacuum system makes too much light for the object scintillator.  This ion gauge should be left off except when actually monitoring the vacuum level.+The ion gauge for the [[Stations|Object station chamber]] vacuum system makes too much light for the object scintillator.  This ion gauge should be left off except when actually monitoring the vacuum level.
  
  
 ===== Target Chamber ===== ===== Target Chamber =====
  
-The venting and pumping of the target area vacuum chamber is taken care of by the experimenters.  Since this chamber is always shifting between two typical configurations (the arrangement for SeGA with just a beamline and the arrangement with the large scattering chamber), the status of the system as displayed on the PanelMate control page may not be reliable at any given time. The readout from the ion gauge should be fed into the PanelMate for either configuration.  The state display and the ability to control the two beamline gatevalves, I246GV and I255GV, should also be functioning in PanelMate for either configuration, but the interlock status display and the interlock functionality to protect from opening either gatevalve at the wrong time may not be set up correctly.+The venting and pumping of the target area vacuum chamber is taken care of by the experimenters. Since this chamber is always shifting between different configurations, the status of the system as displayed on the PanelMate control page may not be reliable at any given time.
