The Second Horizontal Control Survey of the Booster Monument Network
- Brookhaven National Laboratory (BNL), Upton, NY (United States)
A network of survey control monuments, installed in the Booster tunnel, is used as a geodetic reference to define the locations of the Booster machine magnets in the tunnel. The horizontal positions of the monuments were established in the initial control survey, of July 1989, prior to installation of the magnets. In the autumn of 1990 additional radiation shielding was installed between the AGS and Booster machines, increasing floor loading in the area of installation. A second horizontal survey of the Booster ring was made between June and October 1990. The Booster ring magnets were initially installed and aligned using 1990 survey monument coordinates for alignment control. Results of the 1990 survey are reported here and are compared to those of the 1989 survey. A coherent monument shift pattern is observed, possibly due to shield load induced soil flow. Further survey work is suggested.
