Step Chronology Date Type Process Changes
#1 before layer formation 1997-02-15 thermal, fluid physical removing of air and some CO2 gas most air but only part of CO2 is removed. Several freeze-thawn cycles of liquid H2O under dynamic primary vacuum (pumping)
#2 before layer formation 1997-02-15 fluid physical evaporation at ~20°C of liquid H2O from liquid to gas phase
#3 during layer formation 1997-02-15 layer formation liquid condensation of H2O at 293K under its vapor pressure from gas to liquid phase
