　　It is considered that the plasma breakdown is relevant to the initial density of free electrons.An electron injection system via ExB drift aimed at increasing the initial free electrons is designed and constructed on the J-TEXT tokamak to investigate this effect.Early Cxperiments demonstrated that the system works well and some improvement has been obtained at start-up scenano.
