New Mass Spectrometers for NBC & Environmental Characterization

这个项目的目标是建立和调整两个新的质谱(MS)原型:1)一个小,高女士宽容的旋转磁场(RFMS)可以测量气体和液体在一个小,手持包,允许该设备用于实时分析,和2)非常高分辨率multi-bounce飞行时间(MBTOF)女士的适度规模,但随着thecapability测量各种特定heavyisotopes同位素除了光。对于第一个（RFMS）原型，这种现有设计存在与电离器或动量滤波器相关的信噪比（SNR）问题。该团队将使用现成的（OTS）电离器来追踪问题并纠正问题。对于第二个系统，现有的设计将根据广泛的化合物进行校准，以说明测量的准备情况。第二个（MBTOF）原型的具体任务将包括：集成适用于同位素测量的更高速度和灵敏度的ETP混合mcp离散dynode探测器，以及针对一系列化合物的校准和灵敏度测试。该项目研究了与复杂质谱仪新实现相关的基础离子物理学，这些质谱仪可用于广泛的科学和商业学科，在广泛的环境中，从揭示气候历史的冰井到排放气体监测站。

The goal of this project is to build and calibrate two new mass spectrometer (MS) prototypes: 1) A small, high-impact tolerant rotating field MS (RFMS) that can measure gases and fluids in a small, hand-held package, allowing this device to be used for real-time analyses in the field, and 2) An extremely high-resolution multi-bounce time of flight (MBTOF) MS of moderate size, but with thecapability of measuring a wide range of light isotopes in addition to specific heavyisotopes. For the first (RFMS) prototype, this existing design suffers from signal to noise (SNR) issues associated with the ionizer or the momentum filter. The team will use off-the-shelf (OTS) ionizers to track down the issue and correct the problem. For the second system, the existing design will be calibrated against a wide range of chemical compounds, to illustrate readiness for measurements. Specific tasks for the second (MBTOF) prototype will include: integration of a higher speed and sensitivity ETP Hybrid MCP-discrete dynode detector appropriate for isotope measurements, and calibration and sensitivity testing against a suite of chemical compounds. The project investigates the fundamental ion physics associated with new implementations of sophisticated mass spectrometers that could be used in a wide range of scientific and commercial disciplines, in a wide range of environments, from ice boreholes that reveal the history of climate to effluent gas monitoring stations.
