Abstract

The invention relates to a satellite-borne pulsar X-ray spectrometer which comprises a combined X-ray capillary optical lens and an X-ray energy detector, wherein the combined X-ray capillary optical lens is used for converging X-rays which income in parallel or nearly in parallel to a focus of the lens. The combined X-ray capillary optical lens is composed of a plurality of capillary optical lenses. The X-ray energy detector is used for converting an X-ray light signal to an electric signal and is installed at a position of the focus of the combined X-ray capillary optical lens. The surface of the X-ray energy detector is perpendicular to an optical axis of the combined X-ray capillary optical lens.

Description

technical field [0001] The invention relates to the field of space pulsar detection, in particular to a spaceborne pulsar X-ray energy spectrometer. Background technique [0002] X-ray pulsars are known as the most stable astronomical clocks in nature. The application of X-ray pulsars can achieve high-precision measurement of spacecraft time and position. X-ray-based pulsar navigation is a new astronomical navigation method, and pulsar X-ray detectors are the core components of pulsar navigation. Due to the blocking effect of the atmosphere, the X-rays from pulsars cannot reach the ground, so the X-ray detection of pulsars is mostly carried out on satellites. [0003] The current space-borne pulsar X-ray detector consists of two parts: the optical part for collecting X-rays and the photoelectric conversion part. The optical part for collecting X-rays can use X-ray telescopes or collimators. Since the X-ray radiation intensity of pulsars is very weak, the light collection a...
