Congratulations! Dr. Christian Tusche receives “The Kai Siegbahn Prize 2018”

Dr. Christian Tusche solved the long standing problem of efficient spin- and momentum-resolved photoemission by introducing the concept of spin-resolved momentum microscopy. Using a newly designed instrument, Dr. Tusche pushed this method to a resolution and efficiency that is unsurpassed by conventional ARPES techniques. While this alone represents a major step forward in todays ARPES instrumentation, he further combined this new high-resolution momentum microscope with a novel highly stable imaging spin filter.

The extremely efficient imaging spin-filter and the spin-resolving momentum microscope will have a huge impact on the way spin-resolved photoemission experiments will be carried out in the future at synchrotron facilities, where measurement efficiency is an uttermost priority.
