Description

  • Content Description: It is now generally recognized that a large roll, {approx} 6--7 mr, in a triplet low-{beta} quadrupole, which couples the horizontal and vertical motion of the beam, can significantly reduce the luminosity and impact the operation of the Tevatron. The question then arises, what is the effect of the small rolls of the low-{beta} quadrupoles on the luminosity. They will consider random rolls with a {sigma} = 1,2 and 4mr which can be expected due to errors in the surveys, or changes in alignment after the survey. In the actual operation of the Tevatron they attempt to correct for the coupling and so this study will consider correction schemes and will compare the luminosity, after correction, with a configuration with no rolls.
