摘要：
A slow-positron beam switch system, which comprises a pair of beam deflecting coils and two pairs of Helmholtz coils with magnetic-field directions crossing each other, was tested. A slow positron beam with a beam energy of 400 eV was successfully switched from one direction to another, enabling us to direct slow-positron beams to several experimental stations without breaking the vacuum. Images of the positron-beam observed by phosphor screen with microchannel plate at the down stream of this system were presented.
