The High Energy Density Science Instrument at European XFEL: Application and Status
The High Energy Density science (HED) instrument at the European XFEL will provide unique possibilities for the investigation of near solid density matter at states of extreme excitation. European XFEL is a large research infrastructure currently under construction in the Hamburg metropol region, North Germany. It will provide researchers with free-electron laser radiation in the x-ray range from 0.25 to 25 keV and six initial science instruments dedicated to a variety of x-ray techniques and applications.
First experiments are scheduled for 2016. At the HED instrument intense, coherent, and ultrashort x-ray pulses can be applied to obtain structural and electronic properties of highly excited condensed matter in extreme conditions. Excitations will be driven using a variety of optical laser systems. Also pulsed magnetic and electric fields are considered. In addition, the intense FEL pulses can be used for excitation, too. The major science areas addressed by the HED instrument are condensed matter at extreme excitation, solid density plasmas and quantum states of matter. The talk will provide an update on the status of European XFEL, the HED instrument design and describe the scientific applications to be carried out at the HED instrument.
