X-ray pulses for time-resolved experiments on photosensitive systems I - Principles and instrumentation
abstract
Electron accelerators for X-ray production (X-ray free electron lasers - XFEL - and synchrotrons) are able to deliver short (~100 ps at syncrothrons and ~10 fs at XFELs) and bright X-ray pulses [1,2]. If synchronized with optical lasers to trigger a photoreaction, X-rays can provide structural snapshots after the photoreaction with high time (fs) and space (—`) resolution. The basic principles of the approach and their technical implementation will be introduced, in particular for studying biological macromolecules in action [3,4].
Experimental challenges and limitations will also be discussed
