A novel set of superconducting main precession coils has been built and installed in the Jülich-neutron spin-echo (J-NSE) spectrometer at the Heinz Maier-Leibnitz Zentrum (MLZ) in Garching. These unique new coils comprise a field-integral optimizing field shape, fringe field compensation, and high stability. They yield an enhancement of a factor of 2.5 in the intrinsic field-integral homogeneity, i.e., the resolution. The coil concept has been developed for the ESSENSE instrument proposal for the European Spallation Source. We report on the construction of and on the first results from the new superconducting neutron spin-echo spectrometer at the MLZ in Garching where the coils are the main part of a refurbishment of the J-NSE spectrometer after twenty years of operation.
一套新型的超导主进动线圈已制造完成，并安装在位于加兴的亥姆霍兹慕尼黑中心（MLZ）的于利希中子自旋回波（J-NSE）光谱仪中。这些独特的新线圈具有优化场积分的场形、边缘场补偿和高稳定性。它们使固有场积分均匀性（即分辨率）提高了2.5倍。该线圈概念是为欧洲散裂源的ESSENSE仪器提案而开发的。我们报告了位于加兴的MLZ的新型超导中子自旋回波光光谱仪的建造情况和首批结果，在运行了20年后，这些线圈是J-NSE光谱仪翻新的主要部分。
