摘要： Mass spectrometer systems for measuring mass/charge ratios of analytes are described. A mass spectrometer system includes a vacuum flange, a PCB base plate coupled to the vacuum flange, and an ion optic assembly coupled to the PCB base plate. The PCB base plate may include signal-processing electronics. The system may include an electrical cable coupled to the PCB base plate for supplying power, control, and I/O to the ion optic assembly and the signal processing electronics. Alternatively, a mass spectrometer system includes a PCB base plate and an ion optic assembly. The PCB base plate has a sealant portion and an electrical portion. The ion optic assembly is coupled to the electrical portion. The system may include a vacuum housing for enclosing the ion optic assembly. The vacuum housing is coupled to the sealant portion of the PCB base plate for sustaining a vacuum while the system is in operation.

摘要： A focal plane detector assembly of a mass spectrometer includes an ion detector configured to detect ions crossing a focal plane of the spectrometer and an electrically conductive mesh lying in a plane parallel to the focal plane, positioned such that ions exiting a magnet of the mass spectrometer pass through the mesh before contacting the ion detector. The mesh is maintained at a low voltage potential, relative to a circuit ground, which shields ions passing through the magnet from high voltage charges from other devices, such as microchannel plate electron multipliers. The mesh may be mounted directly to the magnet or positioned some distance away. The detector array may include any suitable device, including a faraday cup detector array, a strip charge detector array, or a CCD detector array.

摘要： A detented encoder, employed for sensing a rotation of a wheel by a user between detent position, and suited for use in a pointing device or other user input device. The detented encoder includes a light emitter, a pair of photodetectors, and a codewheel. Interruption of light emitted by the light emitter and received by the photodetectors is processed by a logic circuit to produce a quadrature signal indicative of the detent position of the wheel. The codewheel is integral to a shaft that is supported at one end by a support bracket connected to the lower case of the device. The wheel rotates the shaft when turned by a user. The shaft includes a plurality of evenly-spaced, longitudinally extending spline teeth. A biasing member or opto spacer is operatively coupled to the lower case and includes a base portion on which the light emitter and photodetector are mounted. The biasing member includes a cantilever portion. A U-shaped slot in the cantilever portion includes a protrusion that engages the spline teeth on the shaft. The protrusion is biased against the splined portion of the shaft, so that as the shaft is rotated, the protrusion moves in and out of spline wells defined between adjacent spline teeth, thereby creating a detent action. The detented encoder also includes a microswitch that is activated by the shaft when a user depresses the wheel. A logic device processes the signal produced by the photodetector to determine the transitions between the detent positions as the wheel is turned.
