| Abstract | Since January 1999 routinely about 1 µA of polarized H- ions are delivered for charge-exchange injection into COSY. For protons a polarization of 85 % was routinely achieved. Deuterons with polarizations of 75 % were delivered to experiments offering the choice to receive sequences consisting of eight out of fifteen available different states. By advancing the components of the polarized ion source the number of polarized particles for injection into the cyclotron has been increased by a factor of three to a new record value of 5,5.1012 H- ions, delivered in a 20 ms pulse with a repetition rate of 2 seconds. This report sums up the characteristics of the polarized ion source in its present mode of operation and describes the achievements towards higher beam intensities as well as for providing polarized H- and D-beams with high reliability. |
