A disc sample switching system

Abstract

The application provides a disc-type sample switching system, which includes a shielding box cover, a sample mounting plate and a shielding box body arranged coaxially in sequence; the side of the sample mounting plate facing the shielding box cover has a plurality of sample mounting areas distributed in a circular array The surrounding edge of the sample installation area is provided with a first shielding reed; the shielding box cover is provided with an electromagnetic radiation port; the surrounding edge of the electromagnetic radiation port is provided with a second shielding reed that can be mated with the first shielding reed; There is a third shielding reed on the surrounding edge of the shielding box cover; the end of the shielding box facing the shielding box cover is provided with a fourth shielding reed that can be mated with the third shielding reed; the shielding box is equipped with a first drive mechanism and a second drive mechanism. In this application, the first driving mechanism drives the rotation of the sample mounting plate to realize the switching of the test samples installed on each sample mounting area, without manual replacement of the test samples, and can simultaneously take into account the different electromagnetic wave powers required for different test sample tests.

Description

technical field [0001] The present application relates to the technical field of special ground tests, and in particular to a disc-type sample switching system. Background technique [0002] A large number of multi-layer heat insulation components (MLI) are generally laid on the surface of the spacecraft, and the multi-layer heat insulation components are generally composed of several layers of aluminized film and spacer layers (generally up to 5 to 20 layers). The base material is generally polyester film, the spacer layer is generally polyester thread, flame retardant thread, etc., and the base material of the outer film is generally polyimide material. At the same time, in order to enhance its surface adaptability, it is also carburized on the surface, ITO plated, etc. Craft multilayer insulation components. Under the coupling effect of vacuum and strong electromagnetic field, secondary electron multiplication effect and low-pressure discharge may occur on the surface of...

Problems solved by technology

[0003]Because the process of opening the device (vacuum background establishment) can take several hours, it is difficult to manually replace the effector during the test, and when placing multiple effectors at the same time, It is difficult to take into account the different electromagnetic wave powers required for different effector tests. When using traditional vacuum motors for transmission, it is difficult for the corresponding equipment to survive in complex electromagnetic environments.
