Summary on Grant Application Form |
|
It is proposed that appropriately mounted and deformed silicon membranes be used as X-ray micro-focusing devices. If a silicon membrane, clamped to ensure a boundary of fixed points, is subjected to an electrostatic force by the placement of an electrode underneath, the membrane distorts out of its original planar configuration. The amount and character of the deformation can be controlled by varying the voltage on the electrode and its position. This basic effect can be exploited to produce virtually aberration-free focusing 'lenses' for X-ray beams. Preliminary finite element model calculations show the required ellipsoidal surface may be obtained simply by clamping the membrane in such a way as to describe the perimeter of an ellipse and introducing a single asymmetrically placed electrode.
