Abstract
1443198 Capacitor energising circuits for spectrometry PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 Sept 1973 [29 Sept 1972] 45079/73 Heading H2H An arc emission spectroscopy apparatus comprises a spark gap device in series with a triggered spark gap, the spark gap device being rendered conductive by the triggering of the triggered spark gap, the energy to maintain the spark gap device conductive being obtained from a circuit separate from that which supplies the trigger pulse to the triggered spark gap. A capacitor 5 is charged initially by a pulse # 1 to render thyristor 6 conductive whereupon the capacitor assumes a voltage of -2V AUX . This charging current is oscillatory and when this current reverses a pulse # 2 is applied to a thyristor 8 which then conducts and the capacitor 5 eventually assumes a voltage of 2V TRIG + 2V AUX . The pulse # 2 is simultaneously applied to a thyristor 17 which becomes conductive so enabling a further capacitor 18 to become charged to a voltage of 2V BT plus any residual voltage as the capacitor. A pulse # 3 applied to a thyristor 12 causes the capacitor 5 to discharge into a transformer 13 which triggers a triggered spark gap 15. This gap breaks down with the result that a high voltage wave having a steep wave front is applied to an analytical spark gap 16 which becomes conductive, the charged capacitor 18 then discharging across the ionised gap 16 by way of inductors 23, 21 and diode 24. If desired contacts 28 may be changed over so that the capacitor 18 charges to a voltage of 2V BT + 2V BT <SP>1</SP> and the diode 24 short circuit so that the discharge of the capacitor 18 across the gap 16 is oscillatory. Elements 10, 25 are provided to control the charging of the capacitors 5, 18 respectively.
