1. Timing experiments at current BSRF and future HEPS

Dr Ye Tao (Institute of High Energy Physics)

High Energy Photon Source (HEPS), a near diffraction-limited light source, is planned to be constructed in Beijing in 2018. We will firstly introduce the timing experiment devleopments in current Beijing Synchrotron Radiatino Facility (BSRF), then we will envision the timing experiments in the HEPS with a proposed time-resolved beamline.

4. Applied pump-probe X-ray diffraction at synchrotrons

Synchrotron X-ray sources are among most conventient radiation sources for carrying out time-resolved pump-probe X-ray scattering experiments. Many synchrotron beamlines are currently being equipped with ps and fs lasers to enable laser pump X-ray probe diffraction experiments. At most advanced femtoslicing beamlines the time resolutions below one picosecond is currently achieved. With the...

2. Spatio-temporal coherent control of lattice dynamcis for time-resolved x-ray diffraction

Dr Peter Gaal (Institute for Nanostructure and Solid State Physics)

We employ femtosecond transient grating (TG) spectroscopy to generate and control thermally induced surface deformations. Our sample consists of 60nm Stronthium Titanate on 150 nm Stronthium Ruthenate which is grown on Dysprosium Scandate substrate. We excite the sample with a commercial Titan:Sapphir laser amplifier. The transient grating is generated by imaging a transmission phase mask onto...

3. Time resolved Scanning X-ray Microcopy of Magnetic Nano Structures

Dr Markus Weigand (Max Planck Institute for Intelligent Systems)

Pump and Probe dynamic imaging utilizing the stroboscopic nature of synchrotron light as probe is a powerful tool for investigation of magnetization dynamics. To utilize this method we have built, and since 2010 put in user operation, a soft x-ray transmission microscope at an APPLE II undulator beamline at BESSY II. It combines spatial resolutions of up to 15 nm (limited by zone plate optics)...
