Middle beam current density distribution is the important indicator of assessment electric thrust service life and its plume effect, and faraday probe is to measure space sun
A kind of simple means and method of density profile.
2, gap error is caused the reason is that ion there are a kind of caused error by the gap of collector and protection ring
It injects behind the gap between collector and protection ring due to ion incidence direction or negative bias voltage, ion has part quilt
Collector attracts, and electric current is caused to increase.If the area of gap and collector, than increasing, gap error can also increased.Gap
It is to be determined (five to ten Debye lengths) by the Debye length of working environment, therefore the gap width in working environment is one fixed
Value.Although gap error can be eliminated through formula, best gap compares faraday probe with collector face area
Design on for it is still important.The elimination of gap error is i.e. one of collector wall surface by the way of equivalent cross-sectional area
Part is added on collector face area.The formula of effective sectional area and correction function is given below.
Aequivalent=Ac+KG
A in formulaequivalentIndicate equivalent cross-sectional area, ACFor collector sectional area, KGFor correction function, RGRFor in protection ring
Radius, RCFor collector radius, hGRFor protection ring height, middle hCFor collector height.
Above-mentioned correction function is only theory deduction, but because of the environment in plasma self character and measurement process, position
Factor is set, amendment accuracy is simultaneously unreliable.
Therefore, in scientific research, experiment is needed actually to probe into influence of the gap to probe measurement accuracy.
