摘要:

正电子源是未来直线对撞机项目的关键组成部分。这主要是由于所需的高亮度,比现有的高几个数量级。此外,正电子束的极化大大扩展了机器的物理研究潜力。在这个框架中,康普顿源的极化正电子的生产被考虑在高能量的伽马射线产生的康普顿散射,随后转换成极化的电子-正电子对的目标转换器。康普顿多重相互作用点(IP)线被提出作为增加产生的正电子数的解决方案之一。模拟了康普顿多次激发谱线产生的伽马射线,并将其用于极化正电子的产生。随后,基于绝热匹配装置(AMD)的捕获部分,其次是一个预注入直线加速器进行了模拟捕获和加速的正电子束。

英文摘要:

Positron sources are critical components of the future linear collider projects. This is essentially due to the high luminosity required, orders of magnitude higher than existing ones. In addition, polarization of the positron beam rather expands the physics research potential of the machine. In this framework, the Compton sources for polarized positron production are taken into account where the high energy gamma rays are produced by the Compton scattering and subsequently converted into the polarized electron-positron pairs in a target-converter. The Compton multiple Interaction Point (IP) line is proposed as one of the solutions to increase the number of the positrons produced. The gamma ray production with the Compton multiple IP line is simulated and used for polarized positron generation. Later, a capture section based on an adiabatic matching device (AMD) followed by a pre-injector linac is simulated to capture and accelerate the positron beam.
