Processing steps

Step	Chronology	Date	Type	Process	Changes
#1	before layer formation		thermal	Evaporation of graphite in the condensation chamber by heating through an electrical current, cooling of the vapour by the ambient gas (Ar, 10 mbar), condensation of nanoparticles
#2	during layer formation		layer formation	Extraction of the particles by a jet into the deposition chamber and deposition on the cold CaF2 substrate parallel to Ar gas condensing from a continuous flow, measurement of the particle column density by quartz microbalance
