[dsg-svt] [New Logentry] Additional MFCs for SVT

[beng at jlab.org]

Logentry Text:

Three additional MFCs have been installed for the new N2 cooling setup. Hall B Engineering designed and installed the system, DSG implemented the MFC controls and wiring, and Nathan handled the EPICS/CSS.

One supplies N2 to the L1C area of the SVT (L1C)
Another supplies N2 to the scattering chamber/target/support tube (Tube)
The last is for N2 outside of the SVT between it and the MVT (Outer)

The old N2 supply MFC is now connected to a pump and pulling from inside the SVT.

As with the previous single MFC setup these are controlled via EPICS (normally gas controls are done via the gas shed cRIO and EPICS is only for monitoring/alarms).
