Thermal sublimation of atomic carbon
Refractory metal tube filament filled with ultrapure carbon
Water-cooled power feedthrough
Cooling shroud and shutter optionally available
The Carbon Sublimation Source SUKO-A provides pure, highly reactive atomic carbon with a vast majority of C1 instead of the large percentage of C2 and C3 clusters (~75%) that are naturally released during the sublimation of graphite. The power feedthrough is water-cooled and process safe without any water or vacuum welding seam. |
