Influence of electron cooling on the polarization lifetime of a horizontally polarized storage ring beam
We have shown previously, 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. Here we discuss further tests pointing to additional gains in the IPP lifetime if cooling is active throughout the beam store.
