FEMTOSPEX Molecules and Surfaces

FEMTOSPEX Molecules and Surfaces

An electron spectroscopy setup for time resolved Laser-Pump/x-ray-Probe -experiments is currently being built and in the test phase regarding reproducability, detection solid-angle, efficiency, time resolution, energy resolution, spectrometer factor, and so on.

First results from measurements using the VG Scienta ArTOF and slicing conditions are available,

Sliced and unsliced raw data of Au 4f lines. a) Slicing off b) slicing on c) Difference of a) and b)
