What burns in the sun? Guided tours through the underground laboratory in Dresden's Felsenkeller

Description

The sun generates its energy through the extremely slow fusion of hydrogen into helium, which takes place over billions of years. In order to study these processes in the laboratory, measurements need to be taken in specially shielded locations. The Dresden Felsenkeller, formerly the ice storage facility of the Felsenkeller brewery, is currently the best shielded underground laboratory in Germany. The HZDR and the Technische Universität Dresden operate a small particle accelerator in the historic tunnels VIII and IX - protected from cosmic radiation - to investigate the processes involved in nuclear fusion in the sun, among other things.

The tours take place every 10 minutes from 5 to 11 pm. Free tickets are available on site.

Practical information:
- The special line N6 runs every 45 minutes between the Plauen Nöthnitzer Straße and Felsenkeller stops.
- This year, a snack van will be offering snacks and cool drinks.
