OVERVIEW:
The Chemical Dynamics Beamline at the Advanced
Light Source (ALS) is a national user facility located at the Lawrence
Berkeley National Laboratory. It is devoted to the study of fundamental
chemical processes using vacuum ultraviolet light generated by an undulator
at the ALS. Four endstation ports provide low and medium resolution
outputs in the vacuum ultraviolet, nominally from 7.2-25.4 eV photon energies, with
various fluxes depending on resolution. Several end stations are supported for
experiments in photoionization spectroscopy, ion and electron imaging, flame
studies, clusters, photofragmentation, helium droplet spectroscopy,
radical production, aerosol chemistry, nanoparticle physics and chemical imaging. Potential users can also
bring their own associated equipment to utilize the light outputs for novel
experiments. The beamline is operated and maintained by a group of staff
scientists, post-doctoral fellows, and graduate students. Outside users
collaborate with the beamline staff to perform studies of fundamental chemical
interactions, combustion, interstellar and environmental chemistry, and materials.
The scope of the Chemical Dynamics beamline includes all areas
of chemical physics. New directions in microscopies, aerosol science, kinetics, structure, and dynamics of gas phase, cluster studies, among others, are encouraged.
