Page 15: Analytical System
Analytical system 2.4.1 Detection system The detection system essential comprises the ion source, the magnetic separation system, and the ion collector. The ion source ionizes neutral gas particles from which it generates an ion beam. The positively charged ions are accelerated out of the ion source and subsequently enter the magnetic field. -
Page 16: Mass Spectrometer Supply Msv
2.4.2 Mass spectrometer supply MSV This module produces all voltages and currents required for operating the mass spectrometer: – Anode heating voltage – Cathode heating voltage – Anode potential – Suppressor potential Faults in the mass spectrometer are detected and signaled to the MC 68. The mass spectrometer supply is monitored in MC 68. -
Page 17: Electrometer Pre-Amplifier Evv
2.4.3 Electrometer pre-amplifier EVV The electrometer pre-amplifier converts the current flowing from the ion collector of the mass spectrometer into a voltage signal. It has four amplification stages. The MC 68 control board selects the required amplification stage and processes the analog output signal. The detection limit in the most sensitive range is approximately 1x10 Fig. -
