Backout time in our @tubaf.bsky.social lab! Pumping down to get the chamber ready for upcoming experiments on functionalized metal nanoparticles. Can’t wait to see what charge transfer at hybrid interfaces will reveal. 🔬⚡️ #UHV #Nanoscience

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!

Friedrich Roth @rothlabs.bsky.social · Aug 6

🚨 Big day at the lab! Just installed our brand new laser system from @lightconversion.bsky.social at BESSY II in Berlin – ready to push the limits of ultrafast science. Let the experiments begin! #TUBAF

🚨 Bakeout in progress! The WESPE Endstation is heating up 🔥 and we’re one step closer to commissioning at BESSY II! Just 2.5 weeks to go until first light – can’t wait to kick things off! 💥🧪 #WESPE #BESSYII #SynchrotronScience #UHV #BeamlineReady

Friedrich Roth @rothlabs.bsky.social · Jul 15

🚚 The WESPE endstation has arrived at BESSY II in Berlin-Adlershof!
🔧 Now it’s time for back-out, setup & final checks to get everything ready for commissioning beamtime in early August.
Exciting times ahead!
