| 摘要 |
<p>The present invention relates to a component comprising a tubular structure having interior and exterior surfaces with the interior surface defining an interior passage through the tubular structure, said tubular structure extending longitudinally between opposed ends. The component also includes a resistive film bound to the interior surface of the tubular structure having a pattern configured so that when the resistive film is connected to an electrical source, an electric field is established within the interior passage with an electrical potential that differs along the length of the interior passage while each plane perpendicular to the length of the interior passage is equipotential. Also disclosed are a method of making the component, a charged particle transportation chamber system comprising the component, and a method of identifying and/or separating charged particles.</p> |
