Ion energy analyzer
Web18 mei 2024 · The analyzer is made with a ring electrode of a specific voltage and grounded end cap electrodes. The ions enter the area between the electrodes through one of the end caps. After entry, the electric field in the cavity due to the electrodes causes the ions of certain m/z values to orbit in the space. Web1 dec. 1979 · The analyzer is energy ion scattering (E < 10 keV) face, is shown schematically in fig. continually rotatable from outside (by the use of the system for momentum transfer through UHV envelope), with the accuracy dB ~ 0.3 The possible angular region is 0< B < 140 The detector (CEM) is placed just behind the exit slit of the …
