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.
自莫特（Mott）的原始工作以来，电子自旋极化计的低效率，其落后于光学极化计的程度仍有好几个数量级，这限制了许多基础实验的进行。在这里，我们报告了使用多通道自旋极化分析的新概念来解决这个问题的方法，该方法将效率提高了 4 个数量级。这种改进在使用半球形电子能量分析仪的设置中得到了证明。成像设置证明了并行解析超过 10^5 个数据点的主要能力。
