| Abstract |
The V-I characteristics of low pressure discharges occurring between each of three kinds of anode and a fixed hot cathode in several bi-cusp magnetic fields are investigated. The results are different from those in non-magnetic fields as follows` First, both breakdown and maintaining potentials of low pressure discharges in the fields are rather depend on the arrangement of the directions of magnetic lines of force and the directions between two electrodes than on the distance between two electrodes or the size of the electrodes. Second, the maintaining potentials of the discharges in the fields are lower than those in the non-fields, and the electrical conductivity in the fields are better than those in the non-fields. Third, the breakdown potertials in the fields when the direction of magnetic lines of force is perpendicular with the direction of discharging path between two electrodes are higher than those when the two directions are parallel with each other. But the maintaining patentials in the fields are shown the contrary phenomena with before. This results are particularily conspicuous as the separatrix of the fields pass across the discharging path between two electrodes. |
