BRS vacuum pressure read back signals - End Stations
WP 6652
ERC 170062
The BRS ion pump read back signals are now tied into the vacuum rack. Field cabling from each controller was pulled to connector header H (Pins 37-40) inside the vacuum rack. The Vacuum Controls Chassis was modified to add the new read back signals to terminal 15. Channel 1 is the voltage read back and channel 2 is the pressure read back.
Controllers for the BRS ion pumps are not the same.
End Y - Gamma SPCe controller
End X - MiniVAC Controller

Information for both systems:
BRS-Y
- ion pump is a TiTan 10SW from Gamma Vacuum (PN:10SWCV2HSCNN).
- the controller is a SPCe from Gamma Vacuum (PN:SPC1PS1U1ESNA).
- for the high voltage connection the system uses a SAFECONN type of cable/connectors.
- HV polarity is + (positive)
BRS-X
- ion pump is an old Varian 10 l/s pump.
- the controller is a MiniVac from Varian (PN:EX9290191)
- for the high voltage connection the system uses a FISHER type of cable/connectors.
- HV polarity is - (negative)
