Michele's beamtime on sugars proved very challenging, yet very rewarding and left us with many lessons learned! We specially thank Christophe (beamline scientist) and Rémi (collaborator) for their invaluable help.
The weather was mostly very nice. Here you can see part of the team walking towards the canteen for dinner (left) and the synchrotron laboratory building (right).

The ultra high resolution soft X-ray beamline Pléiades. We have used their hemispherical electron analyzer coupled to a recylcing microjet setup.

Here you can see a macro photograph of the microjet capillary (bottom), the recylcling catcher (top) and the electron analyzer skimmer (facing the camera). The picture on the left was taken when the jet assembly was clean, while the picture on the right was taken after venting the chamber due to freezing of the jet while running a 2 molar sodium iodide solution. The white deposits are the the salt left behind after water evaporated and the electron skimmer was blocked by it, preventing us from collecting electrons. A quick cleaning returned the setup to the state seen on the picture on the left and we were good to go again.

Beamtime @ DESY / Petra III - March 2023
The planets align and Stephan was finally able to join us at the P04 beamline. And Sebastian prepares the new evaporator for not-so-volatile samples (no alanine this time...). Works great!
Karen’s good-bye dinner - March 2023
Good luck Karen. Thank you for the nice and successful two years.
Molecular Physics Department Meeting @ Schloss Ringberg - February 2023
A highlight in the life of the whole department was the three-day outing to Ringberg castle, the conference site of the Max-Planck-Society in the Bavarian Alps. This was the first such meeting after two cancellations during the Covid-19 pandemic.
Henrik Haak updates on flat jet assemblies and the LJ-VMI progress.
News from the FHI Laboratory - February 2023
Moving on with the development of Liquid-Jet Velocity-Map-Imaging (VMI). Still, many technical challanges to be solved, but the main chamber is prepared for the first tests.
Henrik hard at work connecting the cold trap around the VMI assembly, while Bruno watches another of his ingenious designs coming to life.
