The FCAL collaboration has performed a design study for luminometers at\nfuture electronpositron colliders. Compact sampling calorimeters with precisely\npositioned silicon sensors and a fast readout will reach the necessary\nperformance even in the presence of background from beamstrahlung and\ntwo-photon processes. A prototype calorimeter has been built with special focus\non ultra-thin fully instrumented sensor planes to ensure a very small effective\nMoli `ere radius. Preliminary results of measurements in a 5 GeV electron beam\nare presented.\n
