Precision Collimators for High-Energy Radiation Using Foil Wrapping Techniques

The proposed project will demonstrate the feasibility of producing extremely accurate X-Ray collimators at relatively low costs by using precision controlled tape-foil wrapping technique. This technique accurately controls the flatness alignment and slit spacing of these collimator elements by using controlled slat tensions. The proposed technology is an outgrowth of precision wire frame construction methods used on the Gamma Ray Observatory's EGRET experiment. The fabrication is an improvement over the electric discharge wire machining process and hand lay-up methods currently used and provide a superior collimator element compared to laser milled or neutron machined elements.
