Abstract:
Reflection coefficient vs. electron energy measurements have been made for polycrystalline tungsten and tungsten coated stainless steel. A crossed-field trochoidal trajectory method was developed to achieve reliable operation below 1 eV and to accomplish greater versatility in measurement technique. The measurements have been extended from 10 eV down to 0.2 eV. Reflection coefficients increased almost linearly with energy in the 0.2 - 1 eV range. The effects of changes in surface conditions on reflections have been investigated. Values of R ranging from 0.08 to 0.7 were detected. The feasibility of utilizing the trochoidal trajectory method to study ion reflection phenomena is discussed. Author
