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.

电子冷却对水平极化存储环光束极化寿命的影响

先前的出版物表明，COZY存储环中的极化0.97-GeV / c氘核光束的面内极化（IPP）分量可通过束聚，电子和电子的组合获得超过1000 s的极化半衰期。冷却（任何自旋操作之前），六极场调节和光束强度限制。本文记录了进一步的测试，这些测试表明如果在整个光束存储中都处于冷却状态，则可以进一步提高IPP寿命。
