XSdosePES

Photoemission spectroscopy and X-ray absorption are very powerful tools to understand physical, chemical, electronical and structural properties of a broad variety of specimen. However it bears the disadvantage of damaging sensitive samples (see Liquid jet PES).  Even though the very dilute beam at the Station SurICat was already very advantageous for a whole field in research, namely organic polymers, the difficulties in measuring highly sensitive samples remains and often hampers reproducible results.

Within the very recent past a new generation of photoemission detectors (ARTOF) was developed which allows investigations of sensitive sample under extremely mild conditions, i.e. very low photon flux (please see XSdosePES/Suricat) and allowed to speed up the measurements significantly. The photon flux can be reduced by a factor of 10^4 while, at the same time, the acquisition time decreases by at least one order of magnitude.
