Monte Carlo based studies of a polarized positron source for International Linear Collider (ILC)

Ralph Dollan, Karim Laihem, Andreas Schaelicke

摘要:

为了充分发挥国际直线对撞机(ILC)的物理潜能,必须研制出极化正电子束。极化正电子源的新概念是基于圆极化光子源的发展。极化的光子在薄的目标中产生电子-正电子对,并将它们的极化状态转移到输出的轻子上。为了实现高水平的正电子极化,理解靶中的产生机制是至关重要的。因此,目前正在开发一个用GEANT 4模拟极化过程的总体框架。在这方面的贡献,该项目的现状和它的应用研究的正电子生产过程的ILC。

英文摘要:

The full exploitation of the physics potential of an International Linear Collider (ILC) requires the development of a polarized positron beam. New concepts of polarized positron sources are based on the development of circularly polarized photon sources. The polarized photons create electron-positron pairs in a thin target and transfer their polarization state to the outgoing leptons. To achieve a high level of positron polarization the understanding of the production mechanisms in the target is crucial. Therefore a general framework for the simulation of polarized processes with GEANT4 is under development. In this contribution the current status of the project and its application to a study of the positron production process for the ILC is presented.
