European XFEL Science Seminar | Preliminary results from the first user run

Description
Assembling near atomic resolution movies of biological molecules in action is a
key goal of biological imaging using X-ray free electron lasers. Much progress
has been made at existing facilities, however the MHz repetition rate of the
European XFEL promises to hasten progress in this direction by vastly
increasing the rate at which structures can be measured. Additionally, the bright
X-ray pulses open up new modes of molecular imaging.

First experiments at the European XFEL using MHz pulse trains at the SPB
instrument took place in the second half of 2017. Preliminary results indicate
that high quality structural data can be obtained using the MHz pulse trains,
representing a significant step towards high throughput structural determination
using the conventional serial crystallographic approach. Going beyond
crystallography, a more challenging goal is obtaining structures from noncrystalline
molecules or poorly diffracting crystals. We will describe the current
status of non-crystalline X-ray molecular imaging using X-ray free electron
lasers, and discuss the prospects of for single particle biomolecular imaging at
higher pulse repetition rates.
