我们成功地通过实验证明了一个动力结构因子在动量-能量空间中具有多个入射能量的一系列二维映射可以通过一次测量同时获得。该方法减少了飞行时间测量的死区时间，从而显著提高了测量效率。我们在J-PARC使用费米斩波光谱仪4SEASONS所取得的成就有望为非弹性中子散射测量开辟新的可能性。
We succeeded in experimentally demonstrating that a series of two-dimensional maps of a dynamical structure factor in momentum-energy space with multiple incident energies can be simultaneously obtained by one measurement. This method reduces the dead time of time-of-flight Measurement, and thus, it markedly increases the measurement efficiency. Our achievement realized using the Fermi chopper spectrometer 4SEASONS in J-PARC is expected to open up new possibilities of inelastic neutron scattering measurements.
