FIELD: spectral instrument engineering. ^ SUBSTANCE: light source incorporates a generator, a capacitor, a transformer, an electrode-inductor, a central electrode with an axial bore, an amplifier, which, via a matching device, is looped with a negative current feedback circuit to set up and stabilize a required current. Note, also, that the arc and the transformer primary are connected in series with inductor connected to the transformer secondary to ensure a constant phase shift between the arc current and that of inductor. ^ EFFECT: increase in the analysis accuracy. ^ 2 dwg |
