A new generation experiment to measure a limit for the electric dipole moment of the neutron (nEDM) on the 10-28 e.cm level requires magnetic shielding on an unprecedented level. Due to its magnetic moment, the neutron is affected by the earth magnetic field as well as by other ambient magnetic field fluctuations and gradients. This proposal describes the work of a planned co-analsis group, with a detailed plan of experimental and theoretical strategies to study the systematic effects on the measurement of the electric dipole moment of the neutron within the improved OILL-experiment.

在10-28e.cm上测量中子电偶极矩（nEDM）极限的新一代实验需要前所未有的磁屏蔽。由于它的磁矩，中子受到地球磁场以及其他环境磁场波动和梯度的影响。该建议描述了一个计划的共同分析小组的工作，详细计划的实验和理论策略，以研究系统的影响，在改进的OILL实验测量中子的电偶极矩。
