Survey and alignment of the MIT-Bates South Hall Ring

The South Hall Ring (SHR) is a pulse storage/stretcher ring with a circumference of 190 m. The complex contains over 200 magnetic elements, most of which must be positioned to tight tolerances to achieve efficient injection and extraction and to obtain storage times of several seconds for internal targets. In particular, the lattice quadrupoles have transverse position tolerances of ±100 microns magnet-to-magnet, and the circumference has a tolerance of ±5 mm. For the survey and alignment of the ring, we have used automated data capture, data flow and database generation. Alignment of all magnets to approximately ±1/4 mm has been completed. The final survey followed by a smoothing of the lattice will begin soon. The present status and issues of the survey and alignment program will be presented, along with the latest alignment aspects of the beam test results
