AI 中文摘要
CESR注入器直线加速器分六级向康奈尔电子储存环提供正电子:热阴极、150kV直流电子枪、预聚束器、四段电子直线加速器段、钨正电子转换器和四段正电子直线加速器。我们基于开源代码用Python构建了该完整链的端到端模型:WarpX用于空间电荷主导的阴极、电子枪、预聚束器和电子直线加速器,Geant4用于正电子产生,Impact-T用于正电子直线加速器。束流以146MeV到达转换器,回收的正电子被加速至250MeV。各级配置以YAML编写,支持Xopt进行算法调整以实现机器学习优化。
英文摘要
The CESR injector linac supplies positrons to the Cornell Electron Storage Ring in six stages: a thermionic cathode, a 150 kV DC gun, a prebuncher, four electron linac sections, a tungsten positron converter, and four positron linacs. We present a start-to-end model of the full chain, built in Python from open-source codes. WarpX is used for the space-charge-dominated cathode, gun, prebuncher, and electron linacs, Geant4 for positron production, and Impact-T for the positron linacs. The beam reaches the converter at 146 MeV and the recaptured positrons are accelerated to 250 MeV. Stage configurations are written in YAML to allow algorithmic adjustment by Xopt for ML optimization.
