Complete Installation of the Alignment Measurement System; GESAMTANLAGE DES VERMESSUNGSSYSTEMS

Technical Report ·
OSTI ID:4189241
The German Electron Synchrotron consists of 48 magnets which form an acceleration ring with a predetermined radlus of 50.42m. The mean deviation from this ideal radius should not exceed plus or minus 0.1 mm vertically or horizontally. The basic figure of the measurement installation to assure this accuracy is selected to be an octagon. The advantages to be gained by an octagon shape are discussed. In the construction of the measurement posts the effects of temperature variations must be eliminated, and the posts must have the same height and be precisely placed. Inner wires and tapes are used for spacing measurements. The adjustment and testing of the magnets are described and discussed. Height measurements are briefly considered. (J.S.R.)
