Understanding and correcting for systematic effects are essential to successfully pursue a next-generation experiment aiming to measure the neutron EDM to 10-28 e*cm. This proposal outlines a course of action to improve this understanding through the development of simulation, data acquisition and analysis systems for the next-generation neutron EDM experiment at the FRM-II in Munich. The ultimate goal of the simulation effort is to provide a comprehensive numerical framework in which arbitrary electric and magnetic field distortions may be studied to determine their effect on a final neutron EDM measurement. Such a simulation will also contribute to experimental design efforts by providing magnetic cleanliness requirements for critical components, and will eventually be used to provide estimates of systematics by using magnetic characterization data of commissioned experimental pieces. The data acquisition system will combine several sub-systems in a unique approach. Control and monitoring software will be implemented in a layered fashion, combining a view layer, a database layer and a control layer. The view layer, or user interface, will be written using JavaScript and HTML to establish portability and simplicity, and will funnel transactions with the control layer through a database layer to allow persistence of both data and command sequences. Finally, the development of the analysis system will focus on the synthesis of data to remove systematic effects to extract a neutron EDM measurement. In particular, it will aim to harness the wealth of data available in this next-generation approach, using improved co-magnetometry, data from environmental stability monitoring, and estimates from combined characterization data and simulation to reach a measurement goal of 10-28 e*cm.

了解和纠正系统效应对于成功进行下一代实验至关重要，该实验旨在测量10-28 e*cm的中子EDM。该提案概述了通过为慕尼黑FRM-II的下一代中子EDM实验开发模拟、数据采集和分析系统来提高这种理解的行动方针。模拟工作的最终目标是提供一个全面的数值框架，其中可以研究任意电场和磁场畸变，以确定它们对最终中子电火花加工测量的影响。通过提供关键部件的磁性洁净度要求，这种模拟也将有助于实验设计工作，并最终通过使用委托实验部件的磁性表征数据来提供系统估计。数据采集系统将以一种独特的方式结合几个子系统。控制和监控软件将以分层的方式实现，结合视图层、数据库层和控制层。视图层或用户界面将使用JavaScript和HTML编写，以建立可移植性和简单性，并将通过数据库层将与控制层的事务汇集起来，以允许数据和命令序列的持久性。最后，分析系统的开发将侧重于数据的综合，以消除系统影响，以提取中子电火花测量。特别是，它将致力于利用这种下一代方法中可用的丰富数据，使用改进的共磁法，环境稳定性监测数据，以及结合表征数据和模拟的估计，以达到10-28 e*cm的测量目标。
