ILC基线小交叉角方案的改进的最终双重设计
Improved final doublet designs for the ILC baseline small crossing angle scheme
摘要：
ILC基线包括两个相互作用区域，一个具有20mrad交叉角，另一个具有2mrad交叉角。已知的是，在2mrad布局中，在最后的双合透镜和随后的提取线中的出射光束损耗大于在20mrad布局中的出射光束损耗。在这项工作中，我们利用NbTi和Nb $_3$ Sn超导磁体技术，重新设计和优化最终的双合线，目的是在该区域提供令人满意的输出中断束功率损耗。我们提出了三个新的最终的双重布局，专门为500 GeV和1 TeV的机器进行了优化。
英文摘要：
The ILC baseline consists of two interaction regions, one with a 20mrad crossing angle and the other with a 2mrad crossing angle. It is known that the outgoing beam losses in the final doublet and subsequent extraction line are larger in the 2mrad than in the 20mrad layout. In this work, we exploit NbTi and Nb$_3$Sn superconducting magnet technologies to redesign and optimise the final doublet, with the aim of providing satisfactory outgoing disrupted beam power losses in this region. We present three new final doublet layouts, specifically optimised for the 500 GeV and the 1 TeV machines.
