Abstract: A method for controlling the filling of an ion trap with a predetermined quantity of ions. The method comprises generating an ion current by transmitting ions along an ion path to an ion trap, such that ions are accumulated in the ion trap over a transmission time period, wherein the magnitude of the ion current varies in time. The method further comprises detecting at an ion detector at least some ions from the source of ions during a plurality of distinct sampling time intervals interspersed within the transmission time period, and setting the duration of the transmission time period based on the detection of ions at the ion detector.

A controller for controlling the filling of an ion trap with a predetermined quantity of ions and a mass spectrometer comprising the controller is also described.

The logic state circuitry includes logic modules that are reconfigured between application controlled self-test modes in which data is shifted through the logic module and while being powered from the regulated voltage supply signal.
