Mr. Zun Zhang and four PhD students, Yimeng Wang, Jiayun Qi, Siyu Lu, and Yuzhe Sun, recently visited the Institute of Plasma Physics, CAS (Hefei) to deliver the target-type Newton thrust measurement device to Mr. Chang Lei’s group in Room 12 of the Institute of Plasma Physics, CAS to test the N-level thrust of high-power VASMIR and to visit the Plasma Diagnosis Research Laboratory (Room 9).
The delivery included the installation of the target-type thrust measurement device in the vacuum system, thrust calibration and electrical signal measurement processing. The target-type bull-stage thrust measurement device is capable of measuring the thrust of bull-stage thrusters such as high-power spiral waves, and is designed for both open-loop and closed-loop measurements, allowing for steady-state thrust and impulse impulse measurements.

The target-type level thrust measurement device was installed on the same day, and the calibration results showed that the thrust frame had stable performance and could meet the project requirements.
The two sides exchanged views on the structure and principle of the thrust measurement system, working characteristics, working mode, precautions for use and stability of the thrust measurement system.

In the follow-up work, we will improve the problems exposed during the delivery process and optimize the automatic calibration device and closed-loop measurement system to make them more stable and accurate.

We would like to thank Mr. Jan Lei’s team and the testing team at the Institute of Plasma Physics, Chinese Academy of Sciences for their help and support during the installation and testing process.

Members of the group visited EAST
The group visited the laboratory of Mr. Ye Zichong’s team in the Plasma Diagnosis Research Laboratory the next morning and benefited from an in-depth exchange with Mr. Ye on the working principle, system composition, and diagnostic experience of the Laser Induced Fluorescence (LIF) system.
