Hi Scott and Henry , Thanks you for the fat response. I am using copper pins. What is interesting for me is that it really only happens at certain geometries. As long as I don't move chi I can collect for days, if I set chi to let's say 400 and Omega brings the pin to move so that it forms a small angle with respect to the nozzle I get ice. In the Oxford cryo steam manual it gives too small angles between pin and nozzle as one possible reason for ice buildup. I have tried to rearrange the set up as much as possible but have not found a good solution for this.
