MEASUREMENT AND CORRECTION OF THIRD RESONANCE DRIVING TERM IN THE RHIC

PDF Version Also Available for Download.

Description

To further improve the luminosity in polarized proton operation of the Relativistic Heavy Ion Collider, correction of the horizontal two-third resonance at store is desirable. The long-lasting coherent beam oscillations, produced by the AC dipole, are used to measure 3Q,'s resonance driving term h{sub 30000} through the analysis of turn-by-turn beam position data with the algorithm outlined by J. Bengtsson. The resonance driving term h30000 can be compensated with the 12 arc chromatic sextupole families. In this article, we will review the technique of h{sub 30000} resonance driving term's measurement and correction with AC dipole excitation in the RHIC, followed ... continued below
