Ever thought about wanting to do HAXPES but not sure where to start? Well hopefully now you have a useful resource to help you decide where and what you could measure with this exciting technique!

Our review on the state-of-the-art of HAXPES in 2020 is now out in the Journal of Physics: Condensed Matter and it is fully open access for your reading pleasure. This gargantuan effort was spear headed by two fantastic PhD students in the group, Curran Kalha and Nathalie Fernando, who took on a leading role in coordinating efforts and ensuring consistency throughout the paper, beyond contributing their own individual sections to the review paper. We are also particularly proud of Prajna Bhatt, who did her undergraduate literature review in the group and which has become the starting point for one of the sections of the review.

The review would not have been possible without the gargantuan effort by a large team of collaborators and friends including Fredrik Johansson, Andreas Lindblad, Håkan Rensmo, León Zendejas Medina, Rebecka Lindblad, Sebastian Siol, Lars Jeurgens, Claudia Cancellieri, Kai Rossnagel, Katerina Medjanik, Gerd Schönhense, Marc Simon, Alexander Gray, Slavomír Nemšák, Patrick Lömker, and Christoph Schlueter. Our breadth of different experiences across the HAXPES remit has hopefully enabled us to give a comprehensive and balanced overview of machines, systems and applications of HAXPES today.

We are also incredibly grateful for all the beamline scientists and instrument staff at both synchrotrons and in laboratories across the globe who have provided information on existing instrumentation through completing surveys and answering our many questions via email. We hope that the overview we were able to include in the review acts as a selection guide for users to choose the most suitable experimental setup to perform their experiments. There truly is a HAXPES system for everyone! We also hope that this review will act as a point of comparison in the future to benchmark how the technique develops and we hope we can look back in 10 years time (when we might have to write a follow up review) and marvel at all the progress we have made.
