10.4.2017 Beamtime at the U49/2-PGM-1 beamline at BESSY II

This beamtime we further explored metal oxide nanoparticles in water by liquidjet photoelectron spectroscopy. Arno prepared an Fe3O4 nanoparticle solution in our glove box – it is not an easy experiment. Jet stability and concentration are at their limits (and beyond…).

20.3.2017 Beamtime at UE52-SGM-1 beamline at BESSY II

We measured for the first time with our new SOL³PES setup angle-resolved valence photoelectron spectra of neat water. These measurements are key to derive the so-called anisotropy parameter of the outer water valence orbitals. By comparison with gas phase water anisotropy parameter values we can directly determine elastic and inelastic scattering behavior of the outgoing photoelectrons and indirectly the electron mean free path in water – a very important measure for the probing depth. To get our machine to the UE52-SGM-1 beamline we had to use the BESSY crane.

This beamtime was part of the 1st international photonschool at HZB, where 20 international postdocs, master and Phd students got hands-on experience on several experimental BESSY stations, including our SOL³ setup. See more
