Abstract: A wind and temperature spectrometer (WTS) may detect the angular and energy distributions of neutral atoms/molecules and ions in two mutually perpendicular planes. The measured energy distribution at a known angle near the peak may be used to infer the full wind vector W. A WTS having a single ion source may be used in conjunction with a crossed small-deflection energy analyzer (SDEA). The crossed SDEA may combine the angular and energy distributions in the two mutually perpendicular planes into a single spectrometer with a single optical axis. A WTS having a single ion source may use less energy and occupy less space than a WTS with two ion sources.
Abstract translation: 风和温度光谱仪（WTS）可以检测两个相互垂直的平面中的中性原子/分子和离子的角度和能量分布。 在峰附近以已知角度测量的能量分布可以用于推断全风向量W.具有单个离子源的WTS可以与交叉的小偏转能量分析仪（SDEA）结合使用。 交叉的SDEA可以将两个相互垂直的平面中的角度和能量分布组合成具有单个光轴的单个光谱仪。 具有单个离子源的WTS可以使用较少的能量并占据比具有两个离子源的WTS更少的空间。

Abstract: A mass analyzing apparatus and system are disclosed for time-of-flight (“TOF”) mass spectrometry analysis. A representative system includes a first electrostatic mirror prism to reflect a first ion beam and provide an intermediate ion beam having an intermediate TOF focus and having a spatial dispersion of ions proportional to ion kinetic energies; and a second electrostatic mirror prism to reflect the second ion beam and converge the spatial dispersion of ions to provide a third, recombined ion beam having an output TOF focus; and an ion detector arranged at the output TOF focus to receive and detect the ions of the third ion beam. A bandpass filter may be arranged at the intermediate TOF focus to selectively allow propagation of ions of the second ion beam having a selected range of ion kinetic energies. Configurations having additional electrostatic mirror prisms are disclosed, including for tandem MS-MS and selectable time-of-flight.

Abstract: An energy analyzer for Auger electrons can be simply formed by means of a glass tube provided with a helical layer of ruthenium oxide. The loss in energy resolution which occurs upon detection outside the focal plane can be electronically compensated for by detecting the electrons by means of a segmented anode.

Abstract: Devices, systems, and methods for dispersive energy imaging are disclosed. The full three-dimensional velocity distribution function of a flowing particle stream may be measured and properties of the particle stream characterized. In some devices, an aperture system controls the entry of a stream of particles into the sensor where an electrostatic deflector separates the stream of particles into different species, and a detector system senses the separated species.
