Mass spectrometer
First Claim
Patent Images
1. In a mass spectrometer having a resonant-circuit high-frequency electrical power supply for the operation thereof and at least one component which variably detunes the resonance of the circuit and thus the high frequency of the power supply and the operation of the mass spectrometer, the improvement comprising:
- phase detector means for detecting the relative phase of the current and voltage of the power supply;
a transductor in the power supply for varying the resonance and thus the high frequency of the power supply in response to a magnetic flux; and
means responsive to the relative phase detected by the phase detector means and producing the magnetic flux in the transductor in a way which thereby varies the resonance and thus the high frequency of the power supply for retuning the latter.

Abstract
A resonant-circuit, high-frequency electrical power supply for a mass spectrometer has a transductor for magnetically retuning the power supply in response to tuning variations produced by operating variations in the mass spectrometer.
