Atomic Hydrogen Source
Thermal hydrogen cracker
H-flux Atomic Hydrogen Source with optional shutter
The new H-flux Atomic Hydrogen Source* works by thermally dissociating hydrogen in an electron bombardment heated fine tungsten capillary (thermal hydrogen cracker). By bouncing along the hot walls the molecular hydrogen is cracked to atomic hydrogen. This is e.g. very useful for in-situ, damage free cleaning of residual oxygen prior to sample coating (MBE) or analysis. Other applications are in surface modifications appreciating the high reactivity of atomic species.
Atomic Hydrogen can be used in surface science and thin film technolgy ( MBE, GSMBE ) mainly for the following applications:
features of the H-flux Atomic Hydrogen Source
are the zero residual ion current and almost 100% cracking efficiency,
due to the superior and unique Bertel design. Integral watercooling is
included as standard to minimise heat load in the system and
outgassing. A manual shutter is available as option.
shutter: can be operated and closed within
the ID of an DN40CF port.
