Injector Trim Racks
COMMENT ON Perform HCO of Injector 10 Amp Trim Racks
Located Kr Line Vacuum Gauge Cables
This signal is so seldom used that the setup easily fades from memory. I spent a while hunting cables, so I'm documenting it for posterity. There is an adapter cable that transitions from the high density D Sub connector on the MKS gauge to a six-pin circular mil spec that comes down from the tray near chopper 1. This continues through a penetration into rack IN01B03 to a set of terminal blocks which transition it to the serial connector on the front of the 0979 ADC card in rack IN01B05

pump cart checkout, attachment for 1I leak test
Checked CEMs the RGAs for both the large and smaller pump carts in the injector (cart 11, always in the tunnel, and cart 10, moved down from GTS) - (channel electron multipliers for residual gas analyzers)
Found CEM on cart 11 not working with 2 different heads, FC fine but errors come when activating CEM and "burnt" light comes on erronously. This needs attention later.
Found CEM on cart10 is working fine.
Attached cart 10 to beamline at VRV0I01 from other side of beamline to avoid HV cables.
