US 6,389,107 B1 · Capillary polarimeter

Abstract

A system is provided for measuring the polarity and intensity of extreme ultraviolet, soft x-ray, and x-ray radiation. The system comprises a reflective surface, a capillary array, and a detector. The reflective surface is adapted to reflect radiation from a source on to a receiving end of the capillary array. The reflective surface may have a variety of shapes, such as a curved, parabolic shape or a flat shape, for reflecting the radiation in a desired manner. The capillary array may also have a variety of shapes for directing the radiation to the detector, such as a curved shape or a conical shape. The capillaries in the capillary arrays may have an inner diameter that decreases from the receiving end of the array to the emitting end of the array. This increases the flux density of the radiation emitted by the capillary array and helps the detector measure weak radiation.

Dependent claims

A system for measuring the polarization and intensity of extreme ultraviolet, soft x-ray, and x-ray radiation produced by a source, comprising:

(A) a reflective surface, the reflective surface being adapted to reflect the radiation produced by the source, wherein the reflecting surface is adapted to rotate around an axis, the axis being substantially parallel to an incoming path of the radiation reflected by the reflective surface;
(B) a capillary array being adapted to transmit the radiation, the capillary array comprising:
(a) a receiving end positioned to receive the radiation reflected by the reflective surface;
and
(b) an emitting end;
and
(C) a detector positioned to receive radiation emitted by the emitting end of the capillary array, the detector being adapted to measure the intensity of the emitted radiation.
