During recent years Electron Energy Loss Spectroscopy (EELS)has
become established as a leading technique for the investigation
of phonons, adsorbate vibrations and electronic ransitions
at surfaces.
Professor Harald Ibach, Institut für Grenzflächenforschung
und Vakuumphysik, FZ Jülich, Germany, one of the pioneers
and most experienced world experts in this field, designed
and developed an instrument based on a new generation of two
dimensional focussing electrostatic energy dispersive elements.
This resulted in an ultimate resolution of 0.5meV and significantly
increased intensity over the high resolution range.
The instrument is manufactured by Specs under license from
FZ Jülich and is distributed world wide under the name DELTA
