Abstract
Abstract The admission of a gas to a reaction chamber which has been previously evacuated, is followed by its activation via a high-frequency electromagnetic field formed by a composite coil surrounding a material-handling zone within the chamber. The activated gas reacts with material introduced into the chamber and is thereafter withdrawn, along with inactive gas and resultant gaseous byproducts, from the system. The construction of the chamber and the composite coil are such as to provide a substantially uniform distribution of gaseous excited speices throughout the material-handling volume of the chamber.
