The GEC RF Reference Cell is a parallel plate, capacity-coupled, rf plasma reactor that, in principle, is suitable for studies of basic discharge phenomena, investigation of industrial-type plasmas, and theoretical modeling. This report contains 12 articles that review nearly all of the experiments and theoretical modeling efforts that have been performed over the last 5 years using GEC cells. Together, they serve as a "users' guide" to the operation and performance of the GEC cell.
