Title: NSLS-II Booster Survey and Alignment Systems

Abstract

This section outlines the survey and alignment requirements and the technology and tools for achieving the NSLS-II equipment positioning goals. The required alignment tolerances are defined primarily by the physics requirements of the accelerator. The tight tolerances dictated by the physics requirements are an order of magnitude tighter than the tolerances of second generation light sources (NSLS) and on level with those at third generation light sources (Soleil, Diamond). These extraordinary position requirements necessitate a concerted R&D engineering effort to identify and develop the survey methodology needed to meet these requirements. As of this date, the methodology is still evolving to balance cost and time constraints while still maintaining the integrity of the survey and alignment systems. State-of-the art equipment including Laser Trackers and Laser Arms have been purchased and used extensively in the pursuit of meeting the NSLS-II survey tolerances. No new technology will need to be developed to meet the alignment requirements but new techniques will be pursued and developed. Survey and alignment provides the foundation for positioning the beam-guiding magnet structures in all 6 degrees of freedom within the required tolerances. Although the tools and instrumentation available for this task have changed over the years and fastermore » and more accurate measurements are possible, only limited control of the environmental conditions is possible. This ultimately sets an upper limit for the achievable measurement and subsequent control network accuracy. At the same time, the control of environmental variables (temperature, humidity) will be fully taken advantage of during the building of NSLS-II , opening up the possibility of ever-increasing accuracy unheard of only five years ago.« less
