    Abstract: Method for operating a mass spectrometer includes supplying a quantity of ions to an ion detector. The ion detector can include a conversion dynode operating in a first polarity and an electron multiplier. The method further includes adjusting the gain of the electron multiplier to determine a first set of calibration parameters, and calculating a second set of calibration parameters for the electron multiplier from the first set of calibration parameters. The second set of calibration parameters are for a second polarity of the conversion dynode. The method can further include configuring the ion detector to operate at the second polarity based on the second set of calibration parameters, and supplying ions of the second polarity to the mass spectrometer, and detecting an ion at a particular mass to charge ratio using the ion detector.

    Abstract: An anion generating and electron capture dissociation apparatus using cold electrons, which comprises a cold electron generation module configured to generate a large quantity of cold electrons from ultraviolet photons radiated into a mass spectrometer vacuum chamber which is in a high vacuum state has a plurality of ultraviolet diodes configured to emit the ultraviolet photons in the mass spectrometer vacuum chamber. Micro-channel plate (MCP) electron multiplier plates induce and amplify initial electron emissions of the ultraviolet photons from the ultraviolet diodes, and generate a large quantity of electron beams from a rear plate. An electron focusing lens is configured to focus the electron beams amplified through the MCP electron multiplier plates. A grid is configured to adjust energy and an electric current of the electron beams together with the electron focusing lens.

    Abstract: A novel electron multiplier that regulates in real time the gain of downstream dynodes as the instrument receives input signals is introduced. In particular, the methods, electron multiplier structures, and coupled control circuits of the present invention enable a resultant on the fly control signal to be generated upon receiving a predetermined threshold detection signal so as to enable the voltage regulation of one or more downstream dynodes near the output of the device. Accordingly, such a novel design, as presented herein, prevents the dynodes near the output of the instrument from being exposed to deleterious current pulses that can accelerate the aging process of the dynode structures that are essential to the device.
