论文摘要
未来电子峰值线性壁层的当前设计结合了大而复杂的阻尼环，以产生不对称的光束，以进行梁strahlung抑制。在这里，我们介绍了能够在拟议的国际线性线性撞机（ILC）设计中在阻尼环下游产生的电子梁参数可媲美的电子梁的电子喷射器的设计。我们的设计不使用阻尼环，而是基于跨平面相空间操作技术。研究了提出的配置的性能，其对抖动的敏感性以及对自旋极化的影响。提出的范式可以适应其他正在考虑的线性撞机概念，并为降低成本和复杂性提供了一条途径。
The current designs of future electron-positron linear colliders incorporate large and complex damping rings to produce asymmetric beams for beamstrahlung suppression. Here we present the design of an electron injector capable of delivering flat electron beams with phase-space partition comparable to the electron-beam parameters produced downstream of the damping ring in the proposed international linear collider (ILC) design. Our design does not employ a damping ring but is instead based on cross-plane phase-space-manipulation techniques. The performance of the proposed configuration, its sensitivity to jitter along with its impact on spin-polarization is investigated. The proposed paradigm could be adapted to other linear collider concepts under consideration and offers a path toward significant cost and complexity reduction.
