The Hyperbolic Field Analyser (HFA) is a new form of electron energy analyser invented at the University of York. It is a parallel acquisition device with the ability to detect an entire Auger spectrum in under a second. This opens up new areas of research such as spectrum-imaging and the investigation of rapidly altering time dependent processes which are not usually feasible with conventional forms of analysers. Sample beam damage is also reduced, as is sample drift. The analyser uses electrodes to approximate a hyperbolic field, focusing electrons whatever their energy.
