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, reaction of the vapour with H2 from the ambient gas (H2/Ar mixture, volume ratio 1:2, 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
