The HiPP-2 analyser is a based on the Scienta Omicron R4000 10 keV analyser and developed to allow for high pressures at the sample position. This is achieved by the addition of a pre-lens
that combines efficient differential pumping with electron optics, that refocuses the electron paths through the pre-lens. The resulting transmission is at least an order of magnitude better than conventional differential pumping setups.
