[3dem] icing with Gatan ELSA 698

[Tim Gruene]

Hello erveryone,

our Gatan ELSA 698 holder produces ice such that we see the ice rings
in the ED diffraction pattern. The ice evaporates at -130C, but returns
as soon as we reduce the temperature again below about -140C.

This also occurs when we insert the holder at room temperature and only
cool it once fully inserted into the TEM (JEOL JEM2100Plus)

Would there be any ideas for the cause of this icing, and maybe even a
cure?

Thanks a lot!
Best regards,
Tim
