High Energy laser will enable study of exoplanet interiors.
A keenly awaited piece of high-tech equipment has been delivered to European XFEL. The high repetition rate, high-energy laser, DiPOLE 100-X, was developed in the UK by scientists and engineers at the Science and Technology Facilities Council’s Central Laser Facility (CFL) as part of the UK contribution to the facility. This unique laser, developed within the framework of the HiBEF user consortium, will be used at the instrument for High-Energy Density (HED) science at European XFEL to generate extreme temperatures and pressures in materials. The atomic structure and dynamics of these extreme states of materials can then be studied using the extremely bright and intense X-ray pulses produced by the European XFEL. This experimental set-up will enable scientists to create conditions similar to the interior of exoplanets with temperatures of up to 10,000°C, and pressures of up to 10,000 tons per square centimeter – similar to the weight of 2000 adult elephants concentrated onto the surface of a postage stamp!
