Description
The European European X-ray free electron laser (EuXFEL), recently completed in Schenefeld, is one of the brightest X-ray light sources in the world. Generating femtosecond duration X-ray pulses of over 1 mJ per pulse in the hard X-ray regime at a repetition rate of up to 4.5 MHz, it is the first X-ray free-electron laser capable of delivering X-ray pulses with a megahertz inter-pulse spacing, more than four orders of magnitude higher than previously possible. Among many potential applications, the high frame rate is ideal for studying protein dynamics and producing molecular movies of proteins in action. We will look at recent results, applications of X-ray single particle imaging in the light of progress in electron microscopy, and look ahead to what can be achieved using the higher pulse repetition rate available at new facilities such as the EuXFEL and LCLS-II.
