摘要：
The performance of a compact source and a detector of spin polarized electrons is described. The source is based on photoemission induced by circularly polarized laser light from a (110) GaAs surface activated to negative electron affinity (NEA). The detector is a hemispherical low energy Mott analyser in which polarized electrons, accelerated in the radial field of the hemispheres, are scattered from a gold foil at the centre of the spheres and decelerated in the same field before detection at ±120° symmetric angles. Preliminary results of the source and detector performance are presented and an outline of proposed future investigations discussed. © 1990.
