Description
Partial snakes are used at the Brookhaven AGS to avoid strong vertical spin resonances during acceleration of polarized proton beam from 2.5 to 23 GeV. An unfortunate side effect is that these snakes excite numerous weak resonances associated with the horizontal betatron motion. We present experimental demonstration and operational experience of the compensation of these resonances during acceleration by exciting betatron coupling with a set of 15 pulsed skew quadrupoles.
