Research on interference and suppression of electronic drift electric field sensor

摘要

The electronic drift electric field sensor is affected by many factors during the working process, resulting in measurement error. This paper analyzed the measurement error caused by the difference in electron forward motion speed, measurement error caused by magnetic field interference, error caused by changes in charge-to-mass ratio caused by relativistic factors and electron diffraction interference caused by the matter wave effect of moving electrons. On the basis of theoretical analysis, some methods of suppressing interference or correcting errors are proposed for different sources of error.
