Embodiment Construction

[0022] The present invention will be further described now in conjunction with accompanying drawing.

[0023] refer to figure 1 , the pulsar navigation X-ray timing detector of the present invention comprises: a nested cone-shell reflector 1, a magnetic deflector 2 and an X-ray detector 3; Or nearly parallel incident X-rays converge near the conical apex position of the nested conical shell reflector 1; the magnetic deflector 2 is installed at the front end of the X-ray detector 3, and may be incident on the X-ray detector The charged particles of 3 deviate from the X-ray detector 3 to avoid interference to the X-ray detection; the X-ray detector 3 is installed near the cone apex position of the nested conical shell reflector 1, and is used to convert the X-ray optical signal into an electrical signal. signal, and time-stamp the electrical signal.

[0024] The following is a further description of each component in the pulsar navigation X-ray timing detector.

[0025] The n...

Abstract

The invention relates to a pulsar navigation X-ray timing explorer which comprises an embedded conical shell reflection mirror, a magnetic deflector and an X-ray explorer, wherein the embedded conical shell reflection mirror is used for converging parallel or near-parallel incident X-rays from a pulsar to a position near the conical top point of the embedded conical shell reflection mirror; the magnetic deflector is mounted right at the front end of the X-ray explorer, and is used for deflecting charged particles which can possibly enter the X-ray explorer from the X-ray explorer; the X-ray explorer is mounted near the conical top point of the embedded conical shell reflection mirror, and is used for converting an X-ray optical signal into an electric signal, and is used for making a time mark to the electric signal.

Description

technical field [0001] The invention relates to the field of aerospace exploration, in particular to a pulsar navigation X-ray timing detector. Background technique [0002] X-ray pulsar is a kind of X-ray source celestial body, its position coordinates are like a stellar catalog, and the rotation period of X-ray pulsar is extremely stable, so theoretically, pulsar can provide excellent space reference and time reference, for Spacecraft provide natural navigation beacons. X-ray pulsar-based navigation is a new astronomical navigation method, and pulsar X-ray timing detector is the core component of X-ray pulsar navigation. [0003] Since the X-ray radiation intensity of pulsars is very weak, the development of detection instruments with a large effective area is an objective requirement for pulsar navigation. The X-ray pulsar timing detectors currently in orbit basically use collimated gas detectors to meet the detection requirements of large areas. The collimated gas det...
