Magnet Roll Measurements

The magnet roll measurements are used to determine if any twist exists in the magnets. When delivered to the Tevatron, all magnets have their survey lugs adjusted so that the magnet sits level. Any measure of twist indicates a change in the magnetís position after the survey lugs were set. A significant distortion will confuse any understanding of magnetic fields within the magnet.
