Ligit running low (4E-8) all shift. At one point Ernie called in and had me go to the mezzanine to check the flowrate. Also did match the RF impedance as this was off a bit.

WC's did not trip much at start of shift but about half way thru they started tripping non-stop (i.e. once every 10-12 seconds) so a few channel were set to 3800V from 3850V (see elog)

Had to power cycle HV crates once during shift.

Currently we are warming up the nozzle to 300K. Also the RF and the gas has been shut off.

Took runs 4945-4949 all being crunched - but is what is target polarization to be?
