%X In this article, we describe an apparatus for producing a slow-positron beam by moderating the decay positrons from a radioactive source using a W-vane moderator. The integral energy spectrum of the slow-positrons was measured with a retarding field analyser. The results are compared with that obtained using a Ni+MgO moderator at the same apparatus.
