Recent progress in polarized ion sources development is reviewed. New techniques for production of polarized H(-) ion (proton), D(-) (D(+)), and (3)He(++) ion beams are discussed. Feasibility studies of these techniques are in progress at BNL and other laboratories. Polarized deuteron beams will be required for the polarization program at the Dubna Nuclotron and at the deuteron electric dipole moment experiment at BNL. Experiments with polarized (3)He(++) ion beams are a part of the experimental program at the future electron ion collider.

“…The principle of the source is to collide a pulsed polarized hydrogen or deuterium beam with a pulsed neutral Cesium beam having a kinetic energy of about 45 keV [12]. In a charge exchange reaction, taking place in a solenoidal field, negatively charged hydrogen, or deuteron, ions are created and accelerated toward the extraction elements.…”

A polarized atomic-beam target for COSY-Jülich AIP Conf.Abstract. By advancing the components of the polarized negative ion source the number of polarized particles for injection into the cyclotron injector of the cooler synchrotron COSY at the IKP of the Forschungszentrum Jillich has been increased, since 2000, by a factor of three to 5,5x10^^ ff ions, delivered in a 20 milUseconds pulse with a repetition rate of 2 seconds. This report sums up briefly the characteristics of the 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 reUabUity.

The polarized ion source at the cooler synchrotron facility COSY of the research centre Jülich in Germany delivers negative polarized protons or deuterons for medium energy experiments. The polarized ion source, originally built by the universities of Bonn, Erlangen and Cologne, is based on the colliding beams principle, using after an upgrade procedure an intense pulsed neutralized caesium beam for charge exchange with a pulsed highly polarized hydrogen beam. The source is operated at 0.5 Hz repetition rate with 20 ms pulse length, which is the maximum useful length for the injection into the synchrotron. Routinely intensities of 20 µA are delivered for injection into the cyclotron of the COSY facility. For internal targets the intensity of 2 mA and a polarization up to 90% have been reached. Reliable long-term operation for experiments at COSY for up to 9 weeks has been achieved. Since 2003 polarized deuterons with different combinations of vector and tensor polarization were delivered to experiments.
