Description
Technical Field
The invention relates to the technical field of space plasma research and space physical science, in particular to a high-voltage generating circuit, a cleaning system and a method suitable for ionosphere satellite loads.
Background
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
The Retardation Potential Analyzer (RPA) and Langmuir Probe (LP) are common sensors for space plasma detection, and have important significance in ionosphere in-situ detection.
The retarding potential analyzer is of a multi-layer grid structure, and ions with different energy levels can be screened out by configuring the potential of each grid, so that a volt-ampere characteristic curve is formed, as shown in fig. 4.
The langmuir probe, which is a columnar structure and generates a positive or negative potential value with respect to the plasma potential by applying a bias voltage to the metal probe, collects ions or electrons in the plasma to form a voltammetric curve in which the probe bias voltage has a certain relationship with the collected current value, as shown in fig. 5.
The ionospheric plasma probe load is commonly provided with a Langmuir probe, a retardation potential analyzer, an ion drift meter and the like, the surface of the probe load under the ionospheric working condition is clean under normal conditions, and the measured data signal has no hysteresis phenomenon. However, when the plating layer on the satellite surface is damaged by the impact of high-energy particles and pollutes the load sensor, or the load sensor surface adsorbs neutral particles, or the load sensor has a problem of surface oxidation pollution caused by a leak in the protection work of the load in the ground emission pre-stage, the load can cause the deviation of the measurement of the ionized layer plasma data signal by the load, and the detected data and the expected data have obvious difference, which directly influences the reliability and the accuracy of the scientific data detected by the final sensor.
For example: when the problems of adsorption pollution, oxidation pollution and the like occur on the surface of the load sensor, the volt-ampere characteristic curve of the sensor changes, and the characteristic feature is that a hysteresis phenomenon occurs on a periodic scanning signal, namely, the volt-ampere characteristic curve obtained by gradually increasing the potential is inconsistent with the volt-ampere characteristic curve obtained by gradually decreasing the potential, but an obvious shift phenomenon occurs.
The volt-ampere characteristic curve caused by pollution is obviously delayed, so that the invention of key signal characteristics in the volt-ampere characteristic curve is changed, and therefore, ionospheric data obtained by analyzing the polluted curve is accompanied by great errors, and the authenticity, reliability and accuracy of the data are seriously influenced.
For the cleaning work of the pollution of the detection load of the ionized layer, because the special working condition of the satellite cannot provide higher voltage for the circuit, and only a low-voltage direct-current power supply can be provided, so that the traditional method mostly adopts a low-voltage heating mode to carry out the cleaning work of the pollution of the Langmuir probe, namely bias voltage of about ten and a few volts is applied to the probe, or the temperature of the probe is increased by using an external low-voltage heating mode to play a role in cleaning the surface pollution of the probe, however, the traditional method is accompanied with long heating and cleaning time, poor cleaning effect and other adverse factors, and particularly, the cleaning effect on the problems of oxidation, pollutant adsorption and the like is small.
