Here we are describing the experimental realization of the rotating magnetic field neutron spin echo (RFSE) technique that is based on spin turners using truly rotating magnetic fields. RFSE has no practical limit for short Fourier times and a “shorty” instrument mode built on this principle can be easily used at generic neutron spin echo spectrometers to increase their dynamical range beyond that provided by currently used methods.

The upper limit for Fourier times is estimated. The tripling of the field integral (and hence the maximum Fourier time) by means of the bootstrap method is experimentally demonstrated. The suitability of RFSE for the use of Fresnel-type correction elements aiming to equalize the field integral for divergent neutron beams scattered by the sample is shown. The experimental realization of the MIEZE method using the RFSE technique allowing for studies of depolarizing samples and/or with depolarizing sample environments is presented.

在这里，我们将描述基于自旋翻转器的旋转磁场中子自旋回波（RFSE）技术的实验实现，该技术使用了真正的旋转磁场。RFSE对于短傅立叶时间没有实际限制，基于此原理的“短”仪器模式可轻松用于通用中子自旋回波谱仪，以将其动态范围扩大到超出当前使用的方法所提供的范围。

估计傅立叶时间的上限。实验证明了通过自举方法使场积分增加了三倍（从而使最大傅里叶时间）。显示了RFSE对于使用菲涅耳型校正元件的适用性，该元件旨在使样品散射的发散中子束的场积分相等。提出了使用RFSE技术的MIEZE方法的实验实现，该方法允许对去极化样品和/或去极化样品环境进行研究。
