Compensation of depolarizing effects in electron-positron storage rings
Abstract
It is shown that the depolarizing effects in the arc of an electron-positron 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 ± Qx is related to the harmonics of the closed orbit, the strength of the depolarizing resonance [( g - 2)/2] γ = m ± Qz to the harmonics of the vertical betatron oscillations, and the strength of the depolarizing resonance [( g - 2)/2] γ = i ± Qs to the harmonics of the closed orbit and the dispersion orbit. For all these depolarizing resonances compensation schemes are discussed.
