Serving coffee and fresh photons since 1998

The Happy Undulator: Serving coffee, photons and light snacks. Here you can't see a classic image film with a series of images from a synchrotron storage ring, but a funny puppet animation with a clear but subtle message: The Berlin Electron Storage Ring for Synchrotron Radiation has great tools and experimental facilities and whatever users want, at BESSY II they get it. We are happy to share the movie and encourage you as well to send links or likes to anybody who might be interested. Feel welcome and have fun in the "Happy Undulator"!
