Figure 1. Overview of the Compact Light Source (CLS).

Upper image: front view of the CLS showing the injector (on the right), the transport line (on the left) and the electron storage ring (at the top). The length of the CLS is about 5 m. Lower image: CAD drawing of the CLS with the electron storage ring and the optical cavity of the infrared laser system. The interaction point of the laser pulse and the electron pulse is emphasized.
