Crossing integer spin resonance at VEPP-4M with conservation of beam polarization
arXiv:1508.05739 · doi:10.1103/PhysRevAccelBeams.22.112804
Abstract
A method proposed to preserve the electron beam polarization at the VEPP-4M collider during acceleration with crossing the integer (imperfection) spin resonance at energy E=1763 MeV has been successfully applied. It is based on full decompensation of the $ 0.6\times3.3$ Tesla$\times$meter integral of the KEDR detector longitudinal magnetic field due to the anti-solenoids 'switched-off'.
