We report a neutron beam polarization P = [99.9982 ± 0.0024]%, which means an improvement of two orders of magnitude compared to known values. Actually, one can assume this neutron beam to be 100% polarized, because due to the special beam guidance the overlap of spin-up neutrons and spin-down neutrons could be suppressed down to 1.2 × 10 −12 [rel. units]. These values are about four orders of magnitude below the detection limit of a monochromatic neutron flux of 10 8 n· cm −2 s −1 .

实现（几乎）100％的中子束极化

我们报告中子束极化P = [99.9982±0.0024]％，这意味着与已知值相比提高了两个数量级。实际上，可以假定这种中子束是100％极化的，因为由于特殊的束引导，可以将旋转中子和旋转中子的重叠抑制到1.2×10 -12 [相对。单位]。这些值比单色中子通量10 8 n·cm -2 s -1的检测极限低大约四个数量级。
