Omega chamber with EC-UHV transfer system attached (07/2016)

This machine, also called Omega for short, is based on an Omicron Compaqlab UHV system. It consist of a main chamber (preparation and analysis, p<10-10 mbar) and load lock chamber for quick sample loading.

It contains:

Recently it has been extended for transferring samples directly between an electrochemical environment and ultrahigh vacuum without contamination from the ambient atmosphere.

Here picture of the chamber few years ago (that time with bigger Phoibos 150 analyzer). It was used for all the graphene work in our group.
