This photoemission electron microscope is equipped with a new state-of-the-art aberration corrector minimizing electron-optical imperfections and thus, allowing for higher instrument transmission. Simultaneously, better spatial resolution down to 2 nm is achieved as demonstrated in the low-energy (LEEM) mode. In combination with soft x-rays (XPEEM), spatially resolved spectroscopic investigations (NEXAFS, XPS) can be carried out as well as magnetic spectroscopies (XMCD, XMLD). An extension allows performing stroboscopic XPEEM experiments for magnetization dynamics.

This microscope is equipped with a new state-of-the-art aberration corrector minimizing electron-optical imperfections, allowing for higher instrument transmission and simultaneously better spatial resolution. In LEEM-Mode, 2 nm have been demonstrated recently. In combination with soft x-rays (XPEEM), spatially-resolved spectroscopic investigations can be carried out (NEXAFS, XPS) as well as magnetic spectroscopies (XMCD,XMLD). A recently installed extension allows to perform stroboscopic XPEEM experiments for magnetization dynamics.
