Influence of electron cooling on the polarization lifetime of a horizontally polarized storage ring beam (2002.06919v2)
Published 17 Feb 2020 in physics.acc-ph
Abstract: A previous publication has shown that the in-plane polarization (IPP) component of a polarized 0.97-GeV/c deuteron beam in the COSY storage ring may acquire a polarization half-life in excess of 1000 s through a combination of beam bunching, electron cooling (prior to any spin manipulation), sextupole field adjustment, and a limitation of the beam intensity. This paper documents further tests pointing to additional gains in the IPP lifetime if cooling is active throughout the beam store.
