Abstract
PURPOSE:To accomplish the analysis of elements suitable for the spark-line discharge and the arc-like discharge with single lumination by connecting several kinds of discharge energy accumulation circuits different in the time constant in parallel or series to the discharge gap. CONSTITUTION:Discharge energy accumulation circuits different in the time constant respectively comprising rectifying circuits 1 and 2, capacitors C1 and C2, resistances R1 and R2, choke coils L1 and L2, and diodes D1 and D2 are connected in parallel to the discharge gap G. In such a circuit, the time constant and the charging voltage of the capacitors C1 and C2 are selected properly and a trigger voltage is applied to the discharge gap G to discharge. Consequently, a spark-like discharge and an arc-like discharge are continuously produced. In this manner, it is possible to analyze the elements suitable for both types of the discharge simultaneously over one sample with single lumination. In the case of series connection of the energy accumulation circuits, the same effect can be obtained.
