DESY has restarted the free-electron laser FLASH following a 14-month upgrade as part of the FLASH2020+ project. The facility is now optimized for seeded FEL modes with extremely stable and spectrally narrow femtosecond X-ray pulses. I'm excited to use it!

🚀 First XPS spectra with the WESPE endstation at BelChem, BESSY II! 🎉
After wrestling a bit with the external trigger & TDC, the signals are finally looking very promising. Exciting times ahead! 🔬✨

🌟 First Light in the WESPE endstation at BelChem PGM!
After three years of dedication, the tr-XPS endstation at the BelChem PGM beamline @ BESSY II has seen its first light. A huge milestone for the team — the journey into picosecond-resolved science now truly begins!
