Integer spin resonance crossing at VEPP-4M with conservation of beam polarization

A recently proposed method to preserve the electron beam polarization at the VEPP-4M collider during acceleration with crossing the integer spin resonance energy E=1763 MeV has been successfully applied. It is based on full decompensationof $ 0.6\times3.3$ Tesla$\times$meter integral of the KEDR detector longitudinal magnetic field due to s 'switched-off' state of the anti- solenoids.
