抄録

In GAMMA 10, the plasma potential at the plug region, which is generated by fundamental ECRH, is linked to the end plate potential. There are two factors in this linkage. One is the field-aligned flow of warm electrons driven into the loss cone by ECRH. The other is a finite current through the end plate. This current is connected to an ion current, which is detected on annular electrodes in the end mirror cell where the plug potential is formed. An experimental attempt to externally control this current was performed by varying the resistance connecting the end plate to the vacuum vessel, and a picture of current circulation was obtained. In this circuit, ECRH generates an electromotive force by driving the axial flow of electrons. This electromotive force is divided into the positive plug potential and the negative end plate potential, respectively as measured from the vacuum vessel to meet the condition of a closed circuit.
