Thermal vacuum test suitable for space X-ray load whole-satellite

Abstract

The invention discloses a thermal vacuum test suitable for a space X-ray load whole-satellite. The method comprises the following steps: producing X-ray in a vacuum test tank by utilizing secondary targeting of an X-ray light pipe, and then determining that the secondary targeting of the X-ray light tube causes a background, and controlling pollutant in a test process, and finally accomplishing the performance test and processing on the load. Compared with the prior art, multiple radioactive sources can be replaced, different energy band spectral lines can be produced as required, and the on-off control can be performed according to a test demand; the performance test of the X-ray load and the excitation X-ray background control under the whole satellite state are guaranteed, and the pollution in the vacuum thermal test process is controlled, and the safety and the controllability in the whole-satellite thermal vacuum test process is realized.

Description

technical field [0001] The invention relates to a thermal vacuum test method applicable to a space X-ray load whole star, and is applicable to a performance test method during a thermal vacuum test of a whole space X-ray telescope satellite or a single space X-ray telescope. Background technique [0002] Since X-rays cannot penetrate the Earth's atmosphere, space X-ray experiments can only be carried out on rockets or satellites orbiting outside the atmosphere. The same problem also occurs in the ground performance test of space X-ray telescopes. In order to avoid the absorption of X-rays by the ground air, the general performance of X-ray telescopes requires the use of special radioactive sources and special test systems. For the radioactive source method, relevant X-ray radioactive sources need to be specially produced, and they need to be placed relatively close to the telescope detector to form an X-ray source of specific energy. At present, this method mostly uses low r...

AI Technical Summary

Problems solved by technology

Due to the large field of view of the X-ray light tube, it will irradiate the space simulation room and the whole star, and will also generate undesired X-rays, which will form the redundant background of the detector and affect the test results of the satellite.
