A kind of hollow cathode installation optimization method of the hall thruster based on magnetic environment

A kind of hollow cathode installation optimization method of the hall thruster based on magnetic environment, the method for being related to improving hall thruster efficiency can not further increase hall thruster efficiency to solve the problem of that the existing method for improving hall thruster efficiency is single.Measurement hollow cathode potential drop magnetic induction density B corresponding when minimum 0 ；The magnetic induction intensity for determining hall thruster is B 0 Magnetic field isophote coordinate set { (r, z) }；It is advantageously selected for extending the coordinate (r in hollow cathode service life from coordinate set { (r, z) } 0 ,z 0 )；Hollow cathode is placed, the outlet of hollow cathode is made to be placed in (r 0 ,z 0 ) at；Hollow cathode angle is adjusted, the axis and (r of hollow cathode are made 0 ,z 0 ) at magnetic induction line it is tangent.The present invention is suitable for improving the efficiency of hall thruster.
