本文提出一种归一化坐标框架，用于在费米实验室边耦合直线加速器中重建束流横向参数，该方法可最大化丝扫描器测量信息，并适用于复杂光学条件下的束流二阶矩重建。
AI 中文摘要
四极子扫描是束流二阶矩重建的常用工具。由于磁铁强度的限制和束流线元件的布局，简单的四极子-漂移-探测器扫描往往无法收集到足够的数据用于重建。利用归一化坐标框架，我们刻画了稳健的简单四极子扫描所需的前提条件，并将这些前提条件扩展到从更复杂的光学结构中重建。在费米实验室边耦合直线加速器的两个位置，在简单和复杂光学条件下研究了束流二阶矩，利用该框架最大化从丝扫描器剖面测量中获得的信息。
英文摘要
Quadrupole scans are a commonly used tool for beam second moment reconstruction. Limitations in the strength of the magnets and layout of the beamline elements frequently preclude simple quadrupole-drift-detector scans from collecting sufficient data for reconstruction. Using a normalized coordinate framework, we characterize the prerequisites for a robust simple quadrupole scan and expand these prerequisites to reconstruction from more complex optics. The beam second moments are investigated at two locations in the Fermilab Side-Coupled Linac under simple and complex optics, using this framework to maximize information gained from wire scanner profile measurements.
