摘要： The present invention relates to electron multipliers as used in ion detection apparatus such as mass spectrometers. The multiplier comprises a voltage stabilizing component or system, and is configured to reduce a negative effect of voltage fluctuations within and/or electromagnetic radiation emitted by the voltage stabilizing component or system during operation on an output signal of the electron multiplier. The multiplier may be configured so as to decouple the voltage fluctuations within and/or the electromagnetic radiation emitted by the voltage stabilizing component or system from its output signal.

摘要： A photomultiplier tube (PMT) detector assembly includes a PMT and an analog PMT detector circuit. The PMT includes a photocathode configured to emit an initial set of photoelectrons in response to an absorption of photons. The PMT includes a dynode chain with a plurality of dynodes. The dynode chain is configured to receive the initial set of photoelectrons, generate at least one amplified set of photoelectrons, and direct the at least one amplified set of photoelectrons. The PMT includes an anode configured to receive the at least one amplified set of photoelectrons, with a digitized image being generated based on a measurement of the final amplified set of photoelectrons. The digitized image is corrected by applying an output of the signal measured by the analog PMT detector circuit to the digitized image.

摘要： Systems and methods for partial discharge reduction are provided. The systems and methods can receive an input voltage at a high voltage sensor configured within a sealed sensor assembly. The input voltage can be received via a discharge reduction of the sealed sensor assembly. The discharge reduction circuit can reduce an incidence of discharge associated with an ionization breakdown of an air gap between an output circuit of the sealed sensor assembly and an insulator conveying the output circuit through a hermetic barrier of the sealed sensor assembly.

摘要： According to an embodiment, in a CEM assembly and the like, it is possible to reduce a size of a voltage supply circuit configured to stabilize a voltage to be applied to a channel electron multiplier. The CEM assembly includes a CEM and a voltage supply circuit. The CEM includes an input electrode, a multiplication channel, and an output electrode. The voltage supply circuit includes a power source unit and a constant voltage generation unit. A potential of an input electrode A is set by an electromotive force generated by the power source unit. The constant voltage generation unit includes a constant voltage supply unit configured to cause voltage drop. A target potential set at an output-side reference node is maintained by the voltage drop of the constant voltage supply unit.

摘要： A photo cathode converts an incident light into photoelectrons. A photomultiplier kept vacuum inside thereof, amplifies photoelectrons converted by the photo cathode. Photoelectrons intensified by the photomultiplier arrives at an output electrode array, and a current signal produced by the photoelectrons arriving at the output electrode array is directly read outside the photomultiplier via metal bulbs or anisotropic conductive rubber.

摘要： A first amplification unit amplifies at a predetermined amplification rate an output signal from a photodetection unit for detecting an optical signal from a specimen and detecting it. An offset unit assigns offset to an output signal from the photodetection unit. A second amplification unit amplifies at an amplification rate smaller than the amplification rate of the first amplification unit an output signal from the photodetection unit assigned the offset by the offset unit. A rectification unit rectifies an output signal from the second amplification unit. An addition unit adds an output signal from the first amplification unit to an output signal from the rectification unit.
