Abstract
The Femtoslicing beamline at the ALS employs a fs laser beam interacting resonantly with the electron beam in a wiggler. The induced energy spread over the fs duration is converted to a transverse displacement by exploiting the storage ring dispersion. The displaced fs pulse radiates and produces fs synchrotron radiation. Up to now a regular bending magnet was used as radiator. To improve the flux, a significant upgrade was implemented, replacing the modulator, installing an in-vacuum undulator as new radiator, and installing a higher repeptition rate laser system. The new beamline will provide 100-200 fs long pulses of soft and hard x-rays with a repetition rate of 10-40 kHz for experiments concerning ultrafast dynamics in solid state physics, chemistry and biology.
