Description

A rotating target wheel system built for the Atlas Positron Experiment (APEX) is described. It is designed so that targets could withstand the heating caused by the energy loss of intense heavy ion beams. A unique feature is the use of a digital encoder to provide logic trigger signals for beam sweeping and event-by-event target location information. Techniques for fabricating targets of tantalum, lead, thorium and uranium and the behaviour of the targets during beam exposure are also discussed. (orig.)
