Compensation of depolarizing effects in electronpositron storage rings
Abstract
It is shown that the depolarizing effects in the arc of an electronpositron storage ring can be minimized by minimizing certain Fourier harmonics of the particle trajectories. In more detail it is shown that the strength of the depolarizing resonance [( g  2)/2] γ = n ± Q_{x} is related to the harmonics of the closed orbit, the strength of the depolarizing resonance [( g  2)/2] γ = m ± Q_{z} to the harmonics of the vertical betatron oscillations, and the strength of the depolarizing resonance [( g  2)/2] γ = i ± Q_{s} to the harmonics of the closed orbit and the dispersion orbit. For all these depolarizing resonances compensation schemes are discussed.
