Description
The present work is part of a research devoted to the development of a method to search for particle EDMs in an existing storage ring (specifically, NICA of JINR). The method belongs to the family of methods built upon the Frozen Spin idea, one of whose features is that the momentary beam polarization vector is orthogonal to the invariant spin axis (the polarization axis); in other words, the beam used in the measurement is essentially “depolarized.” Its being-depolarized is the ground of the spin-decoherence phenomenon, in view of which the notion of spin-coherence-time receives significance (to the above-mentioned method family).
Presented are the results of an investigation of the behavior of the beam polarization upon approaching spin-resonance in a lattice realizing the so-called “Quasi-Frozen Spin” condition. The work is carried out in view of the guiding question of how rapidly the beam energy must approach the resonance value, if the beam is to be depolarized without loss spin-coherence.
