Abstract
A non-conventional positron source using 1.5–20 GeV electron beam impinging on a tungsten crystal oriented along its 〈111〉 axis is described. Computer simulation taking into account photon creation in the crystal, positron generation in a subsequent amorphous target and also positron capture and transport, allowed extensive investigation of this novel type of source. The possible performances are discussed hereafter. Positron yield has been calculated for different operating conditions. Comparisons with classical sources are presented.
