本文给出了用于自旋回波光谱仪的单螺线管及其校正线圈的设计准则。即使在引入优化的校正线圈之后，单个螺旋线圈也不能满足磁场模量的路径积分的非常高的均匀性的要求。然而，在不同的意义上缠绕的四个同心螺旋线圈的构造允许几乎完全校正由于径向延伸和发散的中子束与三个“菲涅尔线圈”型校正线圈的所有错误。
Design criteria for a single solenoid and its correction coils for the use in spin echo spectrometers are given. A single helical coil does not satisfy the requirement for very high homogeneity of the path integrals of the modulus of the magnetic field even after introduction of optimized correction coils. However, a construction of four concentric helical coils wound in different senses allows for virtually complete correction of all errors due to radial extension and divergency of the neutron beam with three “Fresnel-coil”-type correction coils.
