Design of a small electron cyclotron resonance ion source with partially pulsed magnetic field

A small size electron cyclotron resonance ion source to be operating in a pulsed mode has been designed. The main static magnetic field for the confinement is formed by permanent magnets. In addition to these magnets, two small coils are introduced for controlling the magnetic field with a repetition rate synchronized with the pulsed operation of microwave power feeding. One is installed in the middle of the plasma chamber, the other is near the anode electrode.
