ASTRID

ASTRID is a synchrotron facility at Aarhus University that generates intense light beams with tunable wavelengths from ultraviolet to X-ray. Researchers from many countries use the equipment for experiments in biology, materials science, and physics.

The facility began in the 1980s as a dual-mode ring that stored electrons or ions, operating this way until 2013. It was then rebuilt to serve as an accelerator for the newer ASTRID2 system.

Scientists from multiple countries conduct research at ASTRID in fields including biology, molecular physics, and nanoscale condensed matter through international collaborations.

Scientists can submit proposals for beam time access through various programs, with some offering free facility usage for specific research projects. The facility is primarily used by established research groups and universities that gain access through standard application procedures.

The facility uses continuous electron injection to maintain an uninterrupted light beam for experiments. This makes it possible to run measurements without breaks, which simplifies long-term studies.
