Survey Markers Now Being Installed

A number of APS surveying network fiducials are being provided to facilitate alignment of CAT beamline components in the experiment hall. These references include a beam center-line drawn on the floor for each bending-magnet and insertion-device beamline, four survey monuments per sector, and an array of reference markers along each beamline. These markers are described in detail in APS Technical Update No. 6, which is in preparation. As a CAT begins to plan for installation of its various components, it may request assistance in survey and alignment from the APS by contacting one of the Floor Coordinators or the APS User Program Office.
