SUPM033 Development of a Lamb-shift Polarimeter for Polarization Measurement of Pulsed H+/D+ Ion Beams at IMP Yaojie Zhai , Sheng Zhang, Qianyu Jin, Xuezhen Zhang, Liangting Sun (Institute of Modern Physics, Chinese Academy of Sciences). Spin is one of the intrinsic properties of particles. However, there are many incomprehensible problems about it. High energy polarized electron-ion collisions will provide unprecedented conditions for the study of spin physics and lead us to the study on the inner structure of matter and fundamental laws of interactions, and other forefronts of natural science. As the Phase II of the HIAF (High Intensity heavy ion Accelerator Facility) project, Electron-Ion Collider in China (EicC)* is under conceptual design phase. The production, acceleration and collision of polarized ions and electrons are essential for EicC accelerator facility. Therefore, R&D work such as key technologies prototyping has already been initiated. A spin polarized ion source for the production of intense proton and deuterium ion beams with high polarization is under de- velopment at the Institute of Modern Physics (IMP). Polarization is one of the key characteristics for polarized ion beams. To make the polarization measurement more precise, faster and more convenient, a Lamb-shift Polarimeter (LSP) based on nuclear spin filter is under design, which measures the polarization directly behind the ion source. Scheme of the LSP will be presented, the measurement process, simulations for crucial physical questions and design and test of the key components will be discussed. SUPM034 Study on the Production of High Intensity Polarized H and D Atomic Beam Sheng Zhang , Yaojie Zhai, Qianyu Jin, Xuezhen Zhang, Liangting Sun (Institute of Modern Physics, Chinese Academy of Sciences). Polarized beam is an effective tool in basic research. An Electron-ion collider in China (EicC)*, as a future high energy nuclear physics project, has been proposed. Eicc can provide good re- search conditions for precision measurements of the partonic structure of nucleon or nuclei and the study on the interactions between nucleons and so on. High quality polarized beam is helpful to the accurate measurement of the relevant experiment date. Polarized proton and deuterium (H&D) beam source is one of the key technologies for EicC. Based on the atomic beam polarized ion source (ABPIS) scheme, a polarized H&D ion source with polarization more than 0.8 and beam current more than 1mA is under construction at the Institute of Modern Physics (IMP), providing theoretical and technical support for the design and construction of Eicc polarized source. In the ABPIS, the separating magnet ensures the electron polarization and the effective transmission of the atomic beam; the radiofrequency transition(RFT) unit en- sures that the electronic polarization is converted into deserved nuclear polarization. In order to generate high intensity and high polarization H&D atomic beam, these assemblies need to be precisely designed and optimized. In the paper, an effective method for obtaining the optimal
