Random Sextupole Correction
- Brookhaven National Laboratory (BNL), Upton, NY (United States)
The AGS-Booster has a large tune spread and strong random eddy current sextupoles at injection. As a result, particles in the beam may cross four strong imperfection resonances. We correct these four resonances using trim coils in the chromaticity sextupoles. A scheme is presented for determining the strength of these correctors. For random sextupole errors of 10% of the systematic eddy current sextupoles in the dipoles and .1% errors in the chromaticity sextupoles, we find that the maximum pole tip field for these trim coils is about 35 Gauss.
