The calibration device comprises a two-section lifting platform, a translation transportation platform and an interface board. The ground calibration device is reasonable in structural planning and high in integration level, and the requirements of high bearing capacity, large stroke, the lowest table top height and the like required by the space radiation detector in the ground calibration test process can be met. Meanwhile, the device has relatively high compatibility, can meet the calibration test requirements of loads of different types of space radiation detectors, such as an X-ray detector and a space energy measuring device, can realize quick alignment of the calibration platform and a beam ray outlet, meets the requirements of different detectors on different inclination angles of the platform surface of the calibration platform, and is high in practicability. And the control method is easy to implement, contributes to shortening the test time and improving the test efficiency, and is suitable for being popularized and used in the field.

Description

technical field [0001] The invention belongs to the technical field of space detection, and in particular relates to a high-compatibility ground calibration device, which is used for the calibration test of a space radiation detector on the ground. Background technique [0002] The development history of domestic space radiation detectors is relatively early, but large-scale special-purpose space science observations began with the launch of space science pilot projects, such as dark matter particle detection satellites, hard X-ray telescopes and advanced space-based solar observatory satellites. Before the space radiation detector is launched into the sky, a lot of tests need to be carried out on the ground, especially the performance calibration of the detector, such as detector imaging calibration, efficiency calibration, etc. [0003] The ground calibration of space high-energy particle detection is generally carried out under the condition of a beam with a fixed height,...

AI Technical Summary

Problems solved by technology

The existing calibration platform is generally lifted by a scissor-type lifting mechanism. If the support table is too low, the carrying capacity will drop rapidly (mainly because the carrying capacity is usually limited during the lifting stage)

Moreover, there is currently no calibration platform that can adapt to different radiation detectors in China, mainly due to the fact that each detector has different requirements for the indicators of the platform.

Therefore, it is considered to design a highly compatible calibration device, which can achieve high precision and large stroke range under the premise of large load, and at the same time reduce the initial height of the table as much as possible, and provide the function of adjusting the inclination angle of the table, which can shorten the calibration test. time required, and can reduce redundant construction and save money, but it also faces greater challenges
