For the PDX CO/sub 2/ laser experiment. Optical mounts and shutter-window-grating system design

Mechanical design for the PDX CO/sub 2/ Laser Experiment required provision for an optical table on the basement level for laser and source optics, a beam turning table at the same level, and above it (and just below the vacuum vessel), a Shutter-Window-Grating-Assembly. A similar assembly repeated just above the vacuum vessel. Above this a boom supported detector platform terminates the system optics. The optical table was commercially procured and the turning table designed and fabricated at the Laboratory. The Shutter-Window-Grating-Assemblies contained compact mechanical shutters to protect the vacuum windows, remote operated grating rotators (flexible cable drive, and integral mirrors for initial calibration. The detector platform supporting boom was made from non-metallic material with non-magnetic fasteners to eliminate machine magnetic field forces. The boom was also mechanically isolated from the work platform and adjacent diagnostic to minimize vibration effects
