Abstract (en)
[origin: WO2013127701A2] A simplified device for supplying voltage to the cathode of a mass spectrometer has a push-pull converter, a controlled rectifier (8, 10) being present outside the normal rectifier diodes (7, 9). The gate of the first transistor (8) is connected to the second output (30) and the gate of the second transistor (10) to the first output (32) of the transformer. A voltage supply apparatus, consisting of at least one voltage multiplier, is connected to the output of the transformer via capacitors (13, 14, 15) and supplies, inter alia, the emission current measuring apparatus.
