Problems solved by technology

[0004] 1. The collision of neutral gas and fast ions will produce slow ions, which will be accelerated radially and flow back to the front of the thruster, causing corrosion and charge accumulation to the spacecraft
[0005] 2. Since the plume of the Hall thruster is in a plasma state, it has a shielding effect on electromagnetic waves, which may affect the communication on the spacecraft

specific Embodiment approach 2

[0028] Specific implementation manner two: combination figure 2 This embodiment is described in detail. This embodiment is to further explain the device for monitoring the product components in the plume area of ​​the Hall thruster described in the first embodiment. In this embodiment, the signal is also included in this embodiment. The generator 900 and the rectangular signal output by the signal generator 900 trigger the nanosecond pulse laser 600 and the ICCD camera 700 synchronously.

[0029] The ICCD camera and laser are controlled by the same signal generator. The signal generator generates a rectangular wave with a frequency of 100-1000 Hz. The rectangular signal generated by the signal generator is input to the solid-state laser and ICCD, and the laser and ICCD are triggered synchronously. The fluorescence signal captured by ICCD is input into the computer and saved.

Description

Technical field [0001] The invention relates to the monitoring technology of the product components of the Hall thruster. Background technique [0002] As satellites put forward higher requirements for life, the increase in the life of satellite thrusters has become the key. The traditional satellite chemical thruster has a large thrust but a small specific impulse. To increase the life of the thruster, the chemical fuel carried by the satellite must be increased, which increases the satellite launch cost and reduces the effective load. Compared with traditional chemical thrusters, electric thrusters have the advantages of small size, light weight, high specific impulse, and long life. They can reduce the cost of satellite launch and can meet the requirements of the life of the satellite, which has become a research focus of various countries. [0003] At present, Hall thrusters and ion thrusters are the mainstay. Hundreds of electric thrusters have been applied to satellites, mai...
