Magnet polarities in the LHC

We report the results of extensive tests to verify the polarities of Landau damping octupoles (MOF, MOD) and octupole spool correctors (MCO), arc trim skew sextupoles (MSS), and triplet sextupole correctors (MCSX and MCSSX). All octupole circuits that were measured were found to have the expected po...

description We report the results of extensive tests to verify the polarities of Landau damping octupoles (MOF, MOD) and octupole spool correctors (MCO), arc trim skew sextupoles (MSS), and triplet sextupole correctors (MCSX and MCSSX). All octupole circuits that were measured were found to have the expected polarity. All arc skew sextupoles MSS and triplet sextupole correctors MCSX and MCSSX that were measured were found to have reversed polarity with respect to MADX. It is also noted that the triplet quadrupole trims ktqx2, as well as MQS and MQSX, have reversed polarity with respect to MADX.
