使用DIMAD和BDSIM在ILC萃取管线中进行颗粒跟踪
Particle tracking in the ILC extraction lines with DIMAD and BDSIM
摘要：
束流输运的研究对于现代粒子加速器的设计和性能评估具有重要意义。在本文中，我们基准两个当代的代码，DIMAD和BDSIM，后者是一个相对较新的跟踪代码的框架内建立的GEANT 4。我们认为这两个20 mrad和2 mrad提取线的500 GeV的国际直线对撞机（ILC），我们进行粒子跟踪研究的严重干扰后碰撞电子束。我们发现，这两个代码给出了一个几乎等效的描述的光束传输。
英文摘要：
The study of beam transport is of central importance to the design and performance assessment of modern particle accelerators. In this paper, we benchmark two contemporary codes, DIMAD and BDSIM, the latter being a relatively new tracking code built within the framework of GEANT4. We consider both the 20 mrad and 2 mrad extraction lines of the 500 GeV International Linear Collider (ILC) and we perform particle tracking studies of heavily disrupted post-collision electron beams. We find that the two codes give an almost equivalent description of the beam transport.
