Operator: egeis

Long night of questionable data taking

At arrival, beam had just come back after ramping down blast field in order to open V14 and V15 after vacuum valves tripped.

Background was high and Lattice gauges were noisy throughout the night which caused beam current to be lowered successively from 180 to 170 to 150 mA. At end of shift, Gauges were noisy while beam was off.

Genya discovered upon entrance that the Nozzle had never had the temperature set since last night. All last night's polarization data is subsequently useless.
