Run 14 mid-April TPC IFC issues

IFC currents from the inner field cages over the past ~half day:
(plot from Chanaka, via Alexei; west in blue, east in red)

Inner field cage voltage 1 (closest to ring 181, see diagram here) for west and east over the past ~half day:
(plot by Gene)

Other notes:
  • R = V/I seems reasonably constant (measurements aren't at exactly the same time, so there's some fluctuation, but not on the scale of these excursions), so...
    • ...this is not a problem in the Keithley, reading out the currents.
    • ...the current is being lost further up the resistor chain.
  • No issues observed in OFC east nor west, nor in the cathode readings.
