摘要:

在连续电子束加速器的注入器上进行的极化电子-极化正电子实验首次证实了极化电子束在高$Z$靶中诱导的极化韧致辐射产生的极化从电子到正电子的有效转移。在初始电子束动量为8.19 MeV/ $c$的条件下,测量到的正电子极化率高达82%,只受电子束极化率的限制。这种技术将极化正电子的能力从GeV扩展到MeV电子束,并向广泛的社区开放了极化正电子束物理学。

英文摘要:

The Polarized Electrons for Polarized Positrons experiment at the injector of the Continuous Electron Beam Accelerator Facility has demonstrated for the first time the efficient transfer of polarization from electrons to positrons produced by the polarized bremsstrahlung radiation induced by a polarized electron beam in a high-$Z$ target. Positron polarization up to 82\% have been measured for an initial electron beam momentum of 8.19~MeV/$c$, limited only by the electron beam polarization. This technique extends polarized positron capabilities from GeV to MeV electron beams, and opens access to polarized positron beam physics to a wide community.
