Analysis and Correction of the Closed Orbit Distortion for RHIC
- Brookhaven National Lab. (BNL), Upton, NY (United States). Accelerator Development Dept.
This is a review of the RHIC sensitivity to closed orbit distortion and of the errors that are the cause. There are four sections. In the first we review the analytical calculation of the expectation values of the distortion and we compare the results with those obtained with numerical calculation. The expected uncorrected closed orbit distortion is so large to cause some concern for day-one operation of RHIC which is discussed in the second section where methods are proposed for investigation. A summary of all possible known correction methods is given in the third section; as one can see there is still work to be done. Finally the side effects of non-vanishing closed orbit deviations in the sextupole magnets are reviewed and discussed in the last section.
