SURVEY OF THE 25 BEV SYNCHROTRON AT BROOKHAVEN NATIONAL LABORATORY

Technical Report ·
OSTI ID:4279351
The construction of a 25-Bev synchrotron at Brookhaven National Laboratory requires the location of 240 magnets around a circle one half mile in circumference within one tenth millimeter of their specified positions. The special devices and modifications of existing first order surveying instruments adopted to obtain this high precision in the synchrotron survey are described. Length measurements of 33 meter intervals between the control survey stations are being made with a root mean square error of twenty microns and closure adjustments to angle measurements have been 0.08 sexigesimal seconds.
