使用最先进的复杂探测器和监测器对于在加速器/对撞机设施进行高能和核物理实验至关重要。探测器用于监测大型加速器设施(如相干光源)的带电粒子束参数，并用于开发最先进的新型加速器。束流质量和寿命的提高需要仪器的进步，以保证加速器设备的成功运行。因此，尽量减少束线插入装置对束流的影响是此类装置设计和实验准备过程中必须考虑的问题之一。在本文中，我们建议并讨论将这种影响降至最低的路线图。它是利用基本概念和数值模拟发展起来的，我们表明这是一个需要仔细考虑的多阶段、多参数问题。为了说明路线图，使用了顶点定位器探测器(CERN)的真空室。对计算结果进行了讨论，并提出了优化设计的步骤和步骤。所提出的方法可应用于任何光束线插入装置的优化设计，并将有助于下一代粒子/加速器探测器和监视器的发展。
Use of complex state-of-the art detectors and monitors is essential to carry out high-energy and nuclear physics experiments at accelerator/collider facilities. The detectors are used to monitor charged particle beam parameters at large accelerator facilities such as coherent light sources and to develop new state-of-the art accelerators. Improvements in beam quality and lifetime necessitate the advancement of the instrumentation for successful operation of the accelerator facilities. Minimization of the beam-line-inserted devices' influence on the beam is therefore one of the essential considerations during the design of such facilities and the preparation of experiments. In this paper, we suggest and discuss a roadmap to minimize this influence. It is developed using fundamental concepts and numerical modeling, and we show that this is a multi-stage and multi-parametric problem that needs careful consideration. To illustrate the roadmap, the vacuum vessel for the vertex locator detector (CERN) is used. The results are discussed and, using them, the steps and stages of the design optimization are suggested. The suggested procedure can be applied to optimize the design of any beamline insertion device and will contribute to the development of next generation particle/accelerator detectors and monitors.
