    摘要： A security inspection door comprising a narcotic drug/explosive detecting subsystem, a radioactive substance detecting subsystem and a metal detecting subsystem which are provided in a tank body is disclosed, wherein electromagnetic radiation shields are respectively provided around the three detecting subsystems, so that they are isolated from one another and are not interfered with one another. The three detecting subsystems are combined together to form a novel security inspection door, so the narcotic drugs/the explosives, the radioactive substances and the dangerous metal articles can be detected at the same time. Further, electromagnetic radiation shields are respectively provided around the three detecting subsystems, so that the three detecting subsystems are isolated from one another and are not interfered with one another, and thus, the inspection reliability and the inspection accuracy are improved.

    摘要： An array-based ion storage system includes an ion generation section, and an ion storage section having a first end electrode coupled to the ion generation section and having multiple holes, a second end electrode having multiple holes, an intermediate electrode having multiple holes, a first insulator formed as a ring between the first end electrode and the intermediate electrode, and a second insulator formed as a ring between the intermediate electrode and the second end electrode. The ion storage section can be made thinner to facilitate consistency in ion extraction and reduce the spread of an ion mobility spectrum peak. The insulators have a big hole, and the ions cannot bump onto the insulation material during ion vibration or thermal movement in the storage space. Therefore, charge transfer and accumulation at the insulator and the subsequent discharge will not occur, suppressing instability of storage and loss of ions.

    摘要翻译： 基于阵列的离子存储系统包括离子产生部分和离子存储部分，其具有耦合到离子产生部分并具有多个孔的第一端电极，具有多个孔的第二端电极，具有多个孔的中间电极， 第一绝缘体形成为第一端电极和中间电极之间的环，以及在中间电极和第二端电极之间形成为环的第二绝缘体。 离子存储部分可以被制成更薄以促进离子提取的一致性并减少离子迁移谱峰的扩散。 绝缘子有一个很大的空穴，离子在储存空间的离子振动或热运动过程中不会碰到绝缘材料上。 因此，不会发生绝缘体的电荷转移和积聚，并且不会发生随后的放电，从而抑制存储的不稳定性和离子的损失。

    摘要： Disclosed is an ion gate for a dual IMS and method. The ion gate includes an ion source, a first gate electrode placed on one side of the ion source, a second gate electrode placed on the other side of the ion source, a third gate electrode placed on the side of the first gate electrode away from the ion source, a fourth gate electrode placed on the side of the second gate electrode away from the ion source, wherein during the ion storage, the potential at the position on the tube axis of the ion gate corresponding to the first gate electrode is different from the potentials at the positions on the tube axis corresponding to the ion source and the third gate electrode, and the potential at the position on the tube axis corresponding to the second gate electrode is different from the potentials at the positions on the tube axis corresponding to the ion source and the fourth gate electrode. According to the present invention, after sample gas enters the ion gates, charge exchange with reaction ions occurs between the first gate electrode and the second electrode, and positive and negative ions are continuously stored into the storage regions for the positive and negative ions. This leads to an improvement of utility rate of ions. Then, the ions are educed in a step-wise manner from the storage regions for the positive and negative ions by a simple control of a combination of the electrodes.
