| Abstract: | We describe an apparatus for producing a slow-positrons beam by mode-rating the decay positrons from a radioactive source using a Ni+MgO moder-ator.The integral energy spectrum of the slow-positrons was measured witha plane retarding field analyser.The results are compared with those of othergroups in which the Au(Pt,stainless steel)+MgO moderators were used. |

| Keywords: | slow-positrons moderator energy spectrum. |
