Interactive image comparison: FAIR construction site


An interactive picture slider provides new insights and shows the progress on the FAIR construction site. It allows to compare the pictures from the beginning of construction and today. The virtual superimposition of the images makes the process of building the large particle accelerator facility clearly visible.

Several important stages in the construction process can be seen in the picture slider: The tunnel for the SIS100 accelerator ring is under construction, and the transfer building is growing out of the ground. The first experimental cave, the building for the Compressed Baryonic Matter Experiment (CBM) is also taking shape. Viewers can compare the FAIR construction site in 2018 and 2020 themselves.
The drone images were taken during the regular overflights during which the drone videos are recorded to document the construction site. All drone videos can be found here.

FAIR, the Facility for Antiproton and Ion Research, is one of the largest research projects worldwide. FAIR will be used to create and study matter in the laboratory that otherwise only occurs in the universe. Scientists from all over the world expect new insights into the structure of matter and the development of the universe, from the Big Bang to the present day. (LW)
