自从Mott最初的工作以来，电子自旋偏振仪的效率很低，仍然落后于光学偏振仪几个数量级，已经禁止了许多基本的实验。在这里，我们报告了一个解决这个问题，使用一个新的概念，多通道自旋极化分析，提供了一个惊人的效率增加了4个数量级。这种改进在使用半球形电子能量分析仪的装置中得到了证明。成像装置证明了并行分辨超过10（5）个数据点的主要能力。
Since the original work by Mott, the low efficiency of electron spin polarimeters, remaining orders of magnitude behind optical polarimeters, has prohibited many fundamental experiments. Here we report a solution to this problem using a novel concept of multichannel spin-polarization analysis that provides a stunning increase in efficiency by 4 orders of magnitude. This improvement was demonstrated in a setup using a hemispherical electron energy analyzer. An imaging setup proved the principal capability of resolving more than 10(5) data points in parallel.
