The Macro-Molecular
Beam Injector is designed to produce a collimated, scanable, high flux
molecular beam (organic molecules, DNA etc.) with well controlled parameters.
It is further equipped with effective heating to prevent material condensation
at the orifice. The electro-spray inlet system and source design fit
the production of macro-molecular beams.UVH compatible conditions at
the end stage of the molecular beam injector are established with a
multi-stage pumping system. The differentially pumped pressure system
(2 additional differential pumping stages) guarantees a final pressure
at the heatable output aperture (SEM aperture, exchangeable, Standard
Material = Molybdenum) of 2.10-9 mbar. A shutter and an optical chopper
are included in order to control/modulate the gas beam flux
