METHOD FOR STARTING PRESSURE-GRADIENT TYPE PLASMA GENERATOR

摘要

PROBLEM TO BE SOLVED: To provide a method for starting a pressure-gradient type plasma generator by which the occurrence of an abnormal electric discharge by the magnetic field of a focusing coil can be prevented.;SOLUTION: In the method for starting the pressure-gradient type plasma generator 1 having a pressure-gradient type plasma gun 11 and a focusing coil 13 enclosing a short tube part 12 for fixing the pressure gradient type plasma gun 11, gas for assisting electric discharge is introduced into the pressure- gradient type plasma gun 11 to perform low-current electric discharge and then the magnetic field by the focusing coil 13 is generated.;COPYRIGHT: (C)2002,JPO
