Abstract:
Since 2003 measurements of the rolls in all the Tevatron dipoles and quadrupoles have been made. This has been done using digital levels and fixtures. The data can be quickly collected and analyzed during a typical multi week shutdown allowing for corrections to be made to those magnets with rolls greater than 1 milli-radian. By having historical data problem areas in the Tevatron can be identified. This paper presents the basic operations and calibration information for doing a complete set of roll measurements.
