Origami6
HV=+-40V,
CO2 cooling: P_TT_4: 14.9 bar, mf=0.9 g/s
beam on; xy table position x=306 y=74.5

centered

I=17.8µA; old I2C settings; corrected trigger delay (htr); adjusted front-end voltages 

CO2 pressure reduced to 14.9 bar --> temp is about 4K colder
Temp. at pipe inlet (K7) = -18°C
Temp. at pipe outlet (K8) = -21.8°C
