Open the CIPO recordAbstract From the Canadian patent
Provided herein are a device and a method for determining the spin polarization of an electron beam where the device and method contemplate diffusely backscattering the beam from an electron opaque target at a, kinetic energy less than 10,000 electron volts collecting the scattered electrons which may be of a preselected energy range and within a predetermined solid angle relative to the target and the collector and, measuring the number of scattered electrons which were collected.
