Source of polarized ions and polarized beams at the NUCLOTRON

The paper describes the JINR polarized ion source operating by means of the atomic beam method. The results of testing of the plasma ionizer with a storage cell and tuning of high frequency transition units are presented. The source was installed in the linac injector hall of the NUCLOTRON in May 2016. The source was commissioned and used in the NUCLOTRON runs in 2016 and February – March 2017. Polarized and unpolarized deuteron beams as well as polarized proton beam were produced to accelerate in the NUCLOTRON. The polarized deuteron beam with pulsed current up to 3.7 mA has been produced. Deuteron beam polarization of 0.6-0.9 of theoretical values for different modes of high frequency transition units has been measured with the NUCLOTRON ring internal polarimeter for the accelerated deuteron and proton beams.
