The SLS building (detail)

Villigen is home to a national research facility called the Paul Scherrer Institut (PSI). The programs at PSI are varied, ranging from elementary particle physics to the life sciences. Pictured here is a detail of the Swiss Light Source (SLS) building which is definitely the most visually arresting of all the structures around the campus. It is shaped like a donut with an outer diameter of 138 m (472 ft) and a height of 14 m. At night, it looks as if a UFO landed in the farmlands. I'm working on finding a vantage point for a night-time shot.

Die Paul Scherrer Institut (PSI) ist ein "multidisziplinäres Forschungsinstitut für Natur- und Ingenieurwissenschaften" in Villigen. Hier ist ein Foto von die Synchrotron Lichtquelle Schweiz (SLS).
