In recent development in surface and mass spectrometry
an analyzer is required, capable for collecting ESCA,
AES, MXPS, ISS over the sample surface with optimum energy
and imaging resolutions corresponding to a particular
problem. Analyser - Model
|
|
ESA1000 is one of the
most capable and flexible to meet these needs. It also responds
to a growing number of recent developments in the field of imaging
HWR and SWR and can accommodate almost any new swr and image
intensifiers that appear in the field, and is capable with the
combination ESCA and the time of flight sims(TOF). The resolution
power of the energy analyzer - model ESA1000 can be continuously
varied to give optimum collection efficiency and resolution
for a specific application. For this purpose it is possible
to vary both input slit-width and angular acceptance to the
analyzer continuously to give maximum performance.The quality
of the imaging by ESCA is determined by the imaging quality
of the input lens combined with the analyzer focussing properties
as these in turn influence the |
required ratio for the energy resolution.
ESA1000 combines unique focussing properties of the analyzer
with the imaging properties of the lens to give an unparalleled
combined performance. The input lens is equipped with a quadruple
lens to be able to sweep across the sample surface while collecting
ESCA spectra at the optimum settings for the spectra acquisition.
At the exit of the analyzer is a multi-channel detector with
128 channels. The exit area of the ESA1000 can accept detector
geometry up to 50mm active area width and effectively up to
50mm active area width and effectively up to 1000 detector with
50 m pixel spatial resolution. With an output lens it can produce
an energy spectrum with enhanced resolution or combine SIMS
and ESCA in one instrument. |
