AI Technical Summary
The accuracy of electron flow test results in existing gyrotube systems is low, especially in strong magnetic field and ultra-low temperature environments. Infrared temperature detection method is easily affected by ambient temperature, resulting in unstable test results.
By designing a current data acquisition and comparative analysis method under resistance balance conditions in a gyrotube system, and using a current sensor and resistance compensation module, the current data of the electron gun region and the collection electrode region to the ground are monitored in real time, and the landing point of the electron beam trajectory is determined by combining the ratio analysis.
It improves the accuracy and stability of electron beam flow test results, and can accurately determine whether the electron beam deviates from its trajectory without destroying the vacuum or changing the magnetic field distribution. It provides a basis for magnetic field correction and microwave mode control, and reduces economic costs.
