ABSTRACT:
In a mass spectrometer, stabilization control is effected by modulating the unidirectional ion acceleration voltage with a low-amplitude constant-frequency modulation signal, preferably at the frequency of an A.C. source used to energize the instrument, producing an A.C. modulation component in the ion collector output; that modulation component of the output is detected to develop an error signal indicative of the direction of deviation of the acceleration voltage from an optimum condition of maximized output current and the error signal is employed to adjust the acceleration voltage to stabilize operation at the optimum condition. A corresponding control can be effected by modulation of the magnetic field that deflects the ion stream to impinge on the collector.
