Title: Shouyin Zhang: Innovator in Plasma Technology
Introduction
Shouyin Zhang is a prominent inventor based in Portland, OR (US). He has made significant contributions to the field of plasma technology, holding a total of 11 patents. His work focuses on enhancing the efficiency and effectiveness of plasma sources used in various applications.
Latest Patents
One of his latest patents is titled "Internal split Faraday shield for a plasma source." This invention involves an inductively coupled plasma source that includes a conductive shield within the plasma chamber. The purpose of this shield is to reduce capacitative coupling to the plasma. The internal conductive shield is maintained at a potential similar to that of the plasma source, either by a biasing electrode or by the plasma itself. This innovation allows for a wider variety of cooling methods on the exterior of the plasma chamber. Another notable patent is "Imaging and processing for plasma ion source." In this patent, Zhang and his team discovered that energetic neutral particles created by a charged exchange interaction between high-energy ions and neutral gas molecules can reach the sample in an ion beam system using a plasma source. The energetic neutrals generate secondary electrons away from the beam impact point, and methods to address this issue include using differentially pumped chambers below the plasma source to minimize interactions with gas.
