Spectrometers for Molecular Beam Monitoring |
 |
Hiden Analytical introduce a new range of quadrupole
mass spectrometers specifically for molecular beam studies in high
and ultrahigh vacuum environments, the ionisation sources purpose-designed
to encompass applications from single non-aggressive gas beams to
multiple beam monitoring of condensable and reactive vapours. The
water-cooled shroud accessory is added to enable close positioning
to high temperature environments such as K-cell and E-beam evaporation
sources and to heated substrate platforms.
The 300 amu mass range suits many requirements, with mass range
options to 2500 amu available for specialised applications. Typical
applications include monitoring and control in deposition processes,
laser ablation and ionisation investigations, gas/solid surface
interaction studies, thermal desorption. The XBS version for molecular
beam epitaxy processes, for example, monitors and controls up to
8 beam sources simultaneously. A custom engineering service is available
to ensure optimum beam acceptance positioning.
