论文摘要
近年来，激光血浆加速度（LPA）已成为常规RF加速器的有前途替代方案。但是，到目前为止，理论上仅表明产生极化的LPA梁是可能的。 DESY的LEAP（激光电子加速度与极化）项目旨在首次使用前极化等离子体靶标在实验中证明这一点。电子极化将以光子透射极化法测量，该光谱法利用了通过合适的转换器目标通过电子束在通过电子梁的过程中的圆形极化Bremsstrahlung的生产。然后，通过逆转铁吸收器的磁化方向引起的透射不对称，测量光子极化。在此贡献中，介绍了LEAP项目的概述，详细介绍了偏振电子束的产生以及偏振仪的设计和仿真研究。
In recent years, Laser Plasma Acceleration (LPA) has become a promising alternative to conventional RF accelerators. However, so far, it has only been theoretically shown that generating polarized LPA beams is possible. The LEAP (Laser Electron Acceleration with Polarization) project at DESY aims to demonstrate this experimentally for the first time, using a pre-polarized plasma target. The electron polarization will be measured with photon transmission polarimetry, which makes use of the production of circularly polarized bremsstrahlung during the passage of the electron beams through a suitable converter target. The photon polarization is then measured with the aid of transmission asymmetry arising from reversing the magnetization direction of an iron absorber. In this contribution an overview of the LEAP project is presented, detailing the generation of the polarized electron beams along with the design and simulation studies of the polarimeter.
