Abstract: Within an ion pump, accelerated ions leave the center portion of an anode tube due to the anode tube symmetry and the generally symmetrical electric fields present. The apparent symmetry within the anode tube may be altered by making the anode tube longitudinally segmented and applying independent voltages to each segment. The voltages on two adjacent segments may be time varying at different rates to achieve a rasterizing process.

The apparent symmetry within the anode tube may be altered by making the anode tube longitudinally segmented and applying independent voltages to each segment. The voltages on two adjacent segments may be time varying at different rates to achieve a rasterizing process. In various embodiments, one or more wire internal to the anode structure and having a time-varying electric potential may alter the trajectory of the ions leaving the anode tube, as may the shape of the anode near the ends of the anode tube.
Abstract translation: 在离子泵内，由于阳极管的对称性和大致对称的电场存在，加速离子离开阳极管的中心部分。 阳极管中的表观对称性可以通过使阳极管纵向分段并对每个段施加独立电压而改变。 两个相邻段上的电压可以以不同的速率变化以实现光栅化处理。 在各种实施例中，阳极结构内部并且具有随时间变化的电势的一个或多个导线可以改变离开阳极管的离子的轨迹，阳极的形状可以靠近阳极管的端部。

Abstract: In a first embodiment, a spectroscopy device comprises a preheater, an ionizer, and a differential ion mobility spectroscopy (DMS) analyzer. The preheater is disposed to heat inlet air to 150° C. or more. The ionizer is disposed to receive and ionize heated inlet air from the preheater. The differential ion mobility spectroscopy (DMS) analyzer has a reception element configured to detect ionized chemical agents in the inlet air.In a second embodiment, a spectroscopy device comprises a DMS detector and a controller. The DMS detector comprises an ionizer disposed to receive and ionize inlet air at 150° C. or more, and an analyzer disposed to selectively receive ions from the ionizer under varying radio frequency voltage and compensation field voltage. The controller is configured to flag at least one chemical agent as present in the inlet air upon reception of negatively charged ions by the analyzer under corresponding values of the radio frequency voltage and the compensation field voltage.
