ABSTRACT: The Sub-Picosecond Photon Source (SPPS), in operation since May 2003, makes x-ray pulses of 100 fs. Spontaneous radiation originates from a short pulsed electron beam that passes through an undulator at the Stanford Linear Accelerator Center. New techniques characterize the x-rays, the electrons, and the timing jitter in real time. These results provide a framework for discussion of possible strong field experiments at SPPS and at future fourth-generation photon sources like the recently funded Linac Coherent Light Source.

ABSTRACT: The melting dynamics of laser excited InSb have been studied with femtosecond x-ray diffraction. These measurements observe the delayed onset of diffusive atomic motion, signaling the appearance of liquidlike dynamics. They also demonstrate that the root-mean-squared displacement in the [111] direction increases faster than in the [110] direction after the first 500 fs. This structural anisotropy indicates that the initially generated fluid differs significantly from the equilibrium liquid.
