Ag. Suits et al., A DIFFERENTIALLY PUMPED HARMONIC FILTER ON THE CHEMICAL-DYNAMICS BEAMLINE AT THE ADVANCED LIGHT-SOURCE, Review of scientific instruments, 66(10), 1995, pp. 4841-4844
A differentially pumped rare gas cell has been developed to suppress u
ndulator harmonics on the Chemical Dynamics Beamline at the Advanced L
ight Source. Greater than 10(4) suppression of the harmonics has been
demonstrated with no measurable (<5%) attenuation of the fundamental.
The overall design is presented, and vacuum and optical performance ar
e reported. (C) 1995 American Institute of Physics.
