摘要： A novel technique utilizing the precision of printed circuit board design and the physical versatility of thin, flexible substrates is disclosed to produce a new type of ion reflector. A precisely defined series of thin conductive strips (traces) are etched onto a flat, flexible circuit board substrate. Preferably, the thin conductive strips are further apart at one end of the substrate and get increasingly closer towards the other end of the substrate. The flexible substrate is then rolled into a tube to form the reflector body, with the conductive strips forming the rings of the ion reflector. The spacing between the traces, and hence the ring spacing, can be readily varied by adjusting the conductor pattern on the substrate sheet during the etching process. By adjusting the spacing between the rings, the characteristics of the field created by the reflectron can be easily customized to the needs of the user.

摘要： A reflectron for use with a mass spectrometer that focuses ions having different energies contains a conductive end cap that is electrically connected to a first voltage. A conductive surface is electrically isolated from the end cap and connected to a second voltage. This conductive surface cooperates with the conductive end cap to establish an inner region in which a non-linear electric field exists. As a result, ions having different energies enter and exit the inner region at a common opening and, when within the inner region, are reflected without penetrating past the conductive surface.

摘要： A miniature time-of-flight mass spectrometer (TOF-MS) is provided having (1) a gridless, focusing ionization extraction device allowing for the use of very high extraction energies in a maintenance-free design, (2) a miniature flexible circuit-board reflector using rolled flexible circuit-board material, and (3) a low-noise, center-hole microchannel plate detector assembly that significantly reduces the noise (or “ringing”) inherent in the coaxial design. A method is also provided for increasing the collection efficiency of laser-desorbed ions in the TOF-MS. The method includes the steps of providing within the TOF-MS an ionization extraction device having an unobstructed central chamber having a first region and a second region; creating an ion acceleration/extraction field within the first region; accelerating ions within the first region; de-accelerating the ions in the second region; and drifting the ions in a drift region to cause ion dispersion.

摘要： A reflectron capable of focusing an entire mass range of product ions at substantially the same focal point, comprising a plurality of lens plates, each having an opening therein, for generating a non-linear electric field in the reflectron. To generate the non-linear electric field, the voltage applied to each successive lens plate increases non-linearly with respect to its adjacent lens plate. The voltage of the first lens plate having the opening through which the ions first enter the reflectron is set to a low potential and the voltage being applied to each successive lens plate increases in a non-linear manner with the largest voltage being applied to the lens plate furthest from the first lens plate. This non-linear voltage application, to generate the non-linear electric field, can be achieved by coupling a potentiometer between each lens plate and adjusting each potentiometer accordingly. Alternatively, to generate the non-linear electric field, the lens plates may be unequally spaced and an equal voltage may be applied to each lens plate.
摘要翻译：一种反射镜，其能够将基本上相同的焦点处的整个质量范围的产物离子聚焦，包括多个透镜板，每个透镜板在其中具有开口，用于在反射器中产生非线性电场。为了产生非线性电场，施加到每个连续透镜板的电压相对于其相邻的透镜板非线性增加。具有离子首先进入反射器的开口的第一透镜板的电压被设定为低电位，并且施加到每个连续透镜板的电压以非线性方式增加，其中施加到透镜的最大电压板最远离第一透镜板。用于产生非线性电场的非线性电压应用可以通过在每个透镜板之间耦合电位器并相应地调节每个电位器来实现。或者，为了产生非线性电场，透镜板可以不等间隔，并且可以向每个透镜板施加相等的电压。
