摘要

本文介绍了用原子束方法操作的JINR极化离子源。本文介绍了带存储单元的等离子体电离器的测试结果和高频转换单元的调谐。该源于2016年5月安装在NUCLOTRON的直线喷射器大厅。该源已于2016年和2017年2月至3月在NUCLOTRON运行中投入使用。在NUCLOTRON中产生了极化和非极化氘核束以及极化质子束来加速。产生了脉冲电流达3.7 mA的极化氘核束。用NUCLOTRON环形内偏振计对加速氘核和质子束进行了测量，在不同模式的高频跃迁单元中，氘核束的偏振值为理论值的0.6 ~ 0.9。

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.
