dc.description.abstract | We have demonstrated the ability of a nickel elliptical tube to focus the conical ly diverging pattern of x-ray transition radiation. The x-ray TR was produced by passing moderate-energy (60 to 100 MeV) electron beams through targets consisting of thin (1 urn) multiple foils of aluminum and titanium. The foils were placed in a vacuum chamber; perpendicular to the Naval Postgraduate School's linac primary beamline. An elliptical nickel tube, with a length of 30.5 cm, was placed concentric to the axis of the conical photon beam (as defined by the axis of the electron beam) with an entrance and exit of 1.4 m and 1.7 m, respectively, from the source of the TR at the end of the foil stack. The intensity profile was subsequently measured with a linear image detector placed 3.0 m from the exit of the foil stack. Through a series of experiments, taking into account the effects of surface roughness, the nickel elliptical tube demonstrated the ability to collect 3 to 5 times more energy than a cylindrical quartz tube. | en_US |
