| Abstract |
X-ray free electron lasers deliver high intensity femtosecond pulses that yield high resolution diffraction data of nanocrystals before sample destruction. We utilize the new double bunch mode at the LCLS to produce two hard x-ray pulses to study x-ray induced dynamics in xenon nanoclusters. Using the 2-color x-ray pump / x-ray probe scheme we can separate the signal from the x-ray pump and probe pulse. The Bragg scattering signal of the probe pulse shows significant changes in the virtual powder patterns suggesting that the nanometer-sized sample changes significantly within 80 femtoseconds of the pump pulse. |
