摘要： A ring stacked accelerator for use in a mass spectrometer includes a plurality of ring shaped plates arranged in a stack and is electrically coupled to a voltage divider that allows a substantially homogeneous electric field to be produced when the stack is energized. The voltage divider can include resistors and capacitors, where the capacitors are chosen to compensate for parasitic capacitances experienced by the plates. The ring stacked accelerator can be energized using an RF pulse. The ring stack accelerator can include one or more balancing capacitors for correcting effects that cause nonlinearity.

摘要： Mass spectrometers and related methods of making and using the same are disclosed herein that generally involve positioning a blocking or masking element in the path of an ion beam passing through the mass spectrometer so as to selectively block at least a portion of the ions in the ion beam from entering an accelerator. Mass spectrometers and related methods are also disclosed in which an ion beam passing through the mass spectrometer is deflected or otherwise aimed so as to approach a TOF axis of an accelerator at a non-zero angle.
摘要翻译：本文公开了质谱仪及其相关的制造和使用方法，其通常包括将阻挡或掩蔽元件定位在通过质谱仪的离子束的路径中，以便选择性地阻挡离子中的至少一部分离子光束进入加速器。还公开了质谱仪和相关方法，其中通过质谱仪的离子束被偏转或以其它方式瞄准，以便以非零角度接近加速器的TOF轴。

摘要： In some embodiments, a time of flight mass spectrometer can comprise an input orifice for receiving ions, a first ion accelerator stage for accelerating the ions along a first path, at least one ion reflector for receiving said accelerated ions and redirecting said ions along a second path different than the first path, a detector for detecting at least a portion of the ions redirected by said at least one ion reflector, and at least first and second field free drift regions disposed between said first acceleration stage and said detector, wherein said second field free region is disposed in proximity of the detector. In some embodiments, the lengths of the field free drift regions can be selected so as to provide 1st and 2nd order corrections of the time of flight of the ions with respect to variation in their initial positions.
