Abstract :
This study aims at the reconstruction of anode two-dimensional current density distribution in a moving arc root using algebraic reconstruction technique(ART). The principle of the multi-angle slit-cavity electrode is proposed to obtain the linear current distribution of arc root in diverse directions on the basis of work made by Drouet and his cooperators. The iterative reconstructive algorithm associated with ART is introduced. The measured results of linear current distribution in seven directions are processed with the ART algorithm, and two-dimensional current density in arc root is obtained.
