Determination of Octupole and Sextupole Polarities in the LHC

We report the results of measurements to verify the polarity of higher-order corrector elements in the LHC. The polarities of the lattice focusing and defocusing octupoles, spool piece octupole correctors, arc skew sextupole correctors, and interaction region sextupoles have been verified. All were...

Sumario:We report the results of measurements to verify the polarity of higher-order corrector elements in the LHC. The polarities of the lattice focusing and defocusing octupoles, spool piece octupole correctors, arc skew sextupole correctors, and interaction region sextupoles have been verified. All were found to have the expected polarity with the exception of the arc skew sextupoles.
