Possible Depolarization Mechanism due to Low Beta Squeeze

[摘要] Simulations reveal a potential depolarization mechanism during low beta squeeze. This depolarization appears to be driven by a spin tune modulation caused by spin precession through the strong low beta quads due to the vertical fields. The modulation of the spin tune introduces an additional snake resonance condition at {nu}{sub s0} {+-} n{nu}{sub x} - {nu}{sub z}l = integer which while the same numerology as the well known sextupole resonance, can operate in the absence of sextupole elements.
