Current X-ray lasers require facilities that are kilometres long. A cavity-based set-up about 66 metres in length has been developed that uses highly reflective mirrors to enable the generation of high-intensity pulses of narrow-band X-ray radiation. This promises to overcome the limitations of current X-ray lasers.
It is focussed on West Antarctica, home to 30-40% of the global population of Emperor penguins. The animals are amongst the most threatened in the world.
