HV=+-40V,
CO2 cooling: P_TT_4: 18.2 bar, mf=1 g/s
beam on; xy table position x=306 y=76.5
I=19.5µA; old I2C settings; corrected trigger delay (htr); adjusted front-end voltages

Temp. at pipe inlet (K7) = -14°C
Temp. at pipe outlet (K8) = -17°C

Before this run, the front-end voltages (+2.5 and +1.25) were readjusted so that the nominal values appear on MAMBO. (Previously, both were about 50mV too low.) Not sure if this makes a big difference, let's see.
