Abstract:

The NuMI Lambertsons are planned to be installed during this summer’s shutdown, currently scheduled for late August. Before these can be installed, a finalized extraction and beamline geometry needs to be agreed upon so that the stands and Lambertson flanges may be constructed. This note is to describe a set of quadrupole displacements and dipole corrector strengths that will define the geometry such that the flanges may be constructed and the dipoles installed. These displacements and corrector currents are dependent on the reduction of the present H608, H610, and H612 corrector 120 GeV/c levels to approximately zero. An initial installation scheme and corrector currents will be discussed.
