The technical structure of AVS is organized as a matrix. Members can participate in one or more Divisions or Technical Groups, each of which is focused around a major topical area. Members may also participate in Chapters and Student Chapters, which are regional organizations that focus on local area needs.


Prairie Chapter AVS

Advancing the Science and Technology of Materials, Interfaces, and Processing


The American Vacuum Society (AVS) Prairie Chapter is a non-profit, volunteer-based organization dedicated to advancing the science and technology of vacuum, materials, surfaces, interfaces, thin films, and plasmas. The AVS promotes communication, dissemination of knowledge, recommended practices, research, and education in the use of vacuum and other controlled environments to develop new materials, process technology, devices, and related understanding of material properties for the betterment of humanity.
