Short footage: Aerial view of the FLASH facility at DESY
Flight over the DESY site, with the focus on the 260-meter-long FLASH facility. The flight starts above the HASYLAB buildings in the north-east of the DESY site, shows the FLASH experimental hall, the earth-covered tunnel and the 100-meter-long hall with the first segment of the FLASH facility.

Short footage: Location shot of the FLASH experimental hall
Pan shot to the location of the FLASH experimental hall equipped with five measurement stations for the experiments with shortwave ultraviolet radiation of the free-electron laser FLASH.

Short footage: A scientist at a monitor inside the FLASH hall
The quality of the photon beam can be controlled at a workstation which is located in the FLASH experimental hall. The monitor shows the distribution of both the intensity and the wavelengths of the FEL beam after its conversion into visible light by a crystal.

Short footage: Interior view of the FLASH experimental hall
View from top into the FLASH experimental hall, with the "hut" for the optical laser (right) which only is in use for special experiments, and scientists who are operating their experiment.

Short footage: Scientists at their experiment in the FLASH hall
Scientists are working at the assembly of their experiment in the FLASH hall.

Short footage: Work at the undulator in the FLASH tunnel
View on the laser line in the FLASH tunnel during shutdown. In the second section of the FLASH facility the electrons pass the 30-meter-long undulator, a magnet structure in which the laser-like shortwave radiation is generated according to a principle relying on self-amplification (SASE).

Short footage: Acceleration line in the FLASH tunnel
View on the acceleration line in the FLASH tunnel. The first section of the FLASH facility consists of a series of 12-meter-long superconducting modules that accelerate the electrons to the required energy.
