Generation And Use Of 100 fs Hard X-Ray Pulses: BioCARS Participation In The SPPS Project At SLAC/SSRL

July 2003

The X-ray pulse length emitted by synchrotron sources such as the APS is determined by the electron bunch pulse length, which in turn is limited to about 100ps by essential, long-term stability requirements on the electron beam. However, many interesting structural processes in hard and soft condensed matter and in biological systems occur on time scales shorter than 100 ps (Martin and Vos, 1992), which are inaccessible with existing synchrotron sources.
