X-ray Pulse Duration Control in the LCLS

X-ray pulse duration control is critical to exploring the ultra-fast science at an x-ray freeelectron laser (FEL) facility such as the Linac Coherent Light Source (LCLS). The pulse length of a typical electron bunch that drives a self-amplified spontaneous emission (SASE) FEL is limited to the order of 100~200 fs, due to short-bunch collective interactions. Many novel schemes have been proposed...

Ultrafast Single Shot X-Ray Imaging of Magnetic Phase Transitions

We propose an experiment that makes full use of the unique capabilities offered by LCLS to image the critical fluctuations in a ferromagnetic film in the vicinity of its Curie temperature. The high intensity, femtosecond time structure, and coherence of the LCLS x-ray pulses will enable us to record ultrafast consecutive images of critical fluctuations using a newly developed lensless imaging t...

Demonstration of Feasibility of X-Ray Free Electron Laser Studies of Dynamics of Nanoparticles in Entangled Polymer Melts

The recent advent of hard x-ray free electron lasers (XFELs) opens new areas of science due to their exceptional brightness, coherence, and time structure. In principle, such sources enable studies of dynamics of condensed matter systems over times ranging from femtoseconds to seconds. However, the studies of "slow" dynamics in polymeric materials still remain in question due to the characteris...
