Abstract

A differentially pumped rare gas cell has been developed to suppress undulator harmonics on the Chemical Dynamics Beamline at the Advanced Light Source. Greater than 104 suppression of the harmonics has been demonstrated with no measurable (&lt;5%) attenuation of the fundamental. The overall design is presented, and vacuum and optical performance are reported.
