Extract

For the SESAM/SATEM project is for testing and as a first development step a new fully corrected imaging energy filter of the Ω type built. It is incorporated in a 200keV EFTEM equipped with an LaB6 cathode and a objective lens with a spherical and chromatic aberration coefficient of Cs = Cc = 1.2mm. This EFTEM will be used this year by the SESAM project group at the University Tiibungen, Germany and the MPI fur Metallforschung, Stuttgart. At the same time this kind of filter will be also mounted in the final SATEM.

The energy filter is similar to the design of the so-called FHI-filter suggested by Rose and Lanio [1,2] and built at the Fritz-Haber-Institut of the MPG by Krahl [3]. The total length of the proposed filter is half of the FHI-filter and nearly the same as the length of the LEO 912Ω filter.
