The Wien
Mass Filter is used in combination with the Ion
Source IS 40 E for dynamic SIMS/SNMS analysis and Ion Scattering
Spectroscopy (ISS) applications.
Wien Mass Filter for Ion
Source IS 40 E
The Wien Mass Filter is
used for producing a pure ion beam, free from neutral particles.
It eliminates:
-
Ions of unwanted isotopes
-
Ions of impurities
-
Multiple charged ions
-
Neutral particles
The Wien Filter consists of a permanent magnet and a pair of electrostatic deflector plates arranged perpendicular to each other.
Featuers:
-
High dispersion yet small overall dimensions
-
Additional port for differantial pumping
-
Stigmatic correction and beam adjustment included as standard
-
Beam blanking
-
Can be retrofitted on site to existing Ion Sources IS 40 E
-
Bakeable to 250°C
-
Mounting Flange: 2.75" OD (DN38CF)
-
Mass range: greater than 12.5 amu (5 keV), or 2.5 amu (1 keV)
-
Mass resolution: better than 20 at 5 keV
