| 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 with
a plane retarding field analyser.The results are compared with those of other
groups in which the Au(Pt,stainless steel)+MgO moderators were used. |

| Keywords: | slow-positrons moderator energy spectrum |
