Convenient design and implementation of ground calibration experiments of the Omnidirectional Ion Analyzer based on LabVIEW

The Omnidirectional Ion Analyzer is mounted on a Chinese navigation satellite to detect low-energy (5eV～25 keV) ions in the space near geosynchronous orbit. Before the detector in-flight, the ground calibration experiment is the key step to understand the ion detection results in space. According to the calibration experiment requirements of the Omnidirectional Ion Analyzer, a specific calibration experiment process is designed to manipulate the automation of complex experiments, so as to avoid the error caused by manually operating experiment and improve experimental efficiency. Aiming at the calibration experiment of the Omnidirectional Ion Analyzer, the method and program template of using LabVIEW to quickly design the calibration software system were presented, which provides a reference for the complex experimental design similar to the calibration of an ion analyzer and increases program reusability. The experiment results show that the test software runs stably and reliably, reduces the software development cycle, improves test efficiency, and can accurately control the multi-axis turntable and carry out real-time and accurate information processing.
