Is there any better and inspiring place than DESY for having a lab retreat? Definitely, not. Enjoying the fresh air and the harbor atmosphere in the world's best city, we had a great time at the synchrotron. An unforgettable highlight, in addition to the excellent seminars, was a Tour through the XFEL tunnel and construction site. Really curious when we will use the 3.4 km xray laser for our first next-generation experiment.
