Chemical, Biological and Condensed Matter Studies with Ultrafast X-Ray & THz Pulses

May 27-28, 2010

Location: Brookhaven National Laboratory, Bldg. 703, Large Conference Room

Workshop Chair: Dario Arena (BNL)

Ultrafast probes have been developing rapidly across a wide spectral range.  In the x-ray regime, ultrafast probes can reveal details of phase transitions, spin ordering, phenomena, and transient states in chemical reactions and biological processes.  This workshop will address the scientific opportunities available at storage ring sources which can generate ultrashort x-ray bunches with high repetition rates, tunable emission energy, and long-term stability.  Moreover, as the methods selected for generating ultrashort x-ray pulses can also produce strong coherent THz emission, additional topics on THz probes of chemical dynamics and materials processes will be discussed.
