Radio
frequence source and power stage for generation of all relevant signals for the quadrupole
of a mass spectrometer |
1.8 MHz radio frequency
generator, up to 200Vpp, resonant tank circuits for generation of high voltages with high
efficiency
- Resonance by means of motor - controlled variation of inductance of the tank circuit
- A feedback circuit controls the resonance automatically, thus avoiding the influence of
temperature and aging of the electronic parts and the quadrupole itself
- Feedback circuit for a constand RF-voltage between 0 and 2000 Vpp
- Superposed DC-Voltages, partly proportional to the RF-voltage
- High speed analog technics for generation of all DC and feedback voltages
