摘要： A mass spectrometer suitable to measure both positive and negative particles, such as ions for example in a vacuum chamber. This spectrometer is provided with a turnable permanent magnet segment, which provides the gap of a yoke with adequate magnetic flux having the appropriate direction to separate the positive or the negative particles. Changing the polarity adjusts the flight path of the ions. Thus, negatively charged ions and positively charged ions will follow similar flight paths under opposite polarities, permitting the use of a single array of detectors. One or more coils may be used in place of or in addition to the turnable permanent magnet segment in order to provide the appropriate magnetic flux to the gap, and/or facilitate the turning process of the turnable magnet segment. The turnable magnet and/or the coils may be inside or outside the vacuum chamber. The detector may comprise at least one detector area, two charge mode amplifiers coupled to the detector area, a first CCD shift register coupled to a first one of the charge mode amplifiers and a second CCD shift register coupled to a second one of the charge mode amplifiers.

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 charged particle beam detection system that includes a Faraday cup detector array (FCDA) for position-sensitive charged particle beam detection is described. The FCDA is combined with an electronic multiplexing unit (MUX) that allows collecting and integrating the charge deposited in the array, and simultaneously reading out the same. The duty cycle for collecting the ions is greater than 98%. This multiplexing is achieved by collecting the charge with a large number of small and electronically decoupled Faraday cups. Because Faraday cups collect the charge independent of their charge state, each cup is both a collector and an integrator. The ability of the Faraday cup to integrate the charge, in combination with the electronic multiplexing unit, which reads out and empties the cups quickly compared to the charge integration time, provides the almost perfect duty cycle for this position-sensitive charged particle detector. The device measures further absolute ion currents, has a wide dynamic range from 1.7 pA to 1.2 μA with a crosstalk of less than 750:1. The integration of the electronic multiplexing unit with the FCDA further allows reducing the number of feedthroughs that are needed to operate the detector.
摘要翻译：描述了一种包括用于位置敏感带电粒子束检测的法拉第杯检测器阵列（FCDA）的带电粒子束检测系统。 FCDA与电子多路复用单元（MUX）组合，可以收集和积分阵列中的电荷并同时读出。收集离子的占空比大于98％。通过用大量小型和电子去耦法拉第杯收集电荷来实现这种复用。由于法拉第杯独立于充电状态收集电荷，因此每个杯子都是收集器和积分器。与充电积分时间相比，法拉第杯与电子多路复合单元组合的能力与电子多路复用单元相结合，能够快速地清空和提供杯子，这为位置敏感的带电粒子检测器提供了几乎完美的占空比。该器件测量进一步的绝对离子电流，具有1.7 pA至1.2μA的宽动态范围，串扰小于750：1。电子复用单元与FCDA的集成进一步允许减少操作检测器所需的馈通数量。

摘要： A charged particle beam detection system (10) that includes a Faraday cup detector array (FCDA) for position-sensitive charged particle beam detection is described. The FCDA is combined with an electronic multiplexing unit (MUX) (2) that allows collecting and intgrating the charge deposited in the array, and simultaneously reading out the same. The duty cycle for collecting the ions is greater than 98%. This multiplexing (2) is achieved by collecting the charge with a large number of small and electronically decoupled Faraday cups. Because Faraday cups collect the charge independent of their charge state, each cup is both a collector and an integrator. The ability of the Faraday cup to integrate the charge, in combination with the electronic multiplexing unit (2), which reads out and empties the cups quickly compared to the charge integration time, provides the almost perfect duty cycle for this position-sensitive charged particle detector (10). The device (10) measures further absolute ion currents, has a wide dynamic range from 1.7 pA to 1.2 μA with a crosstalk of less than 750:1. The integration of the electronic multiplexing unit (2) with the FCDA further allows reducing the number of feedthroughs that are needed to operate the detector (10).
