National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Analysis of Multipactor Discharge. Final Technical Report, April 2, 1998 - August 31, 2005.

DE2005860178

Publication Date	2005
Personal Author	Lau, Y. Y.
Page Count	26
Abstract	Several comprehensive studies of rf breakdown and rf heating are reported. They are of general interest to magnetic confinement fusion, rf linacs, and high power microwave source development. The major results include: (1) ground-breaking theory of multipactor on dielectric, including a successful proof-of-principle experiment that verified the newly developed scaling laws, (2) in depth investigation of the failure mechanisms of diamond windows and ceramic windows, of the roles of graphitization, thin films of coatings and contaminants, and (3) a most comprehensive theory, to date, on the heating of particulates by an electromagnetic pulse, on the separate roles of rf magnetic field heating and of rf electric field heating, including the construction of new scaling laws that govern them. The above form a valuable knowledge base for the general problem of heating phenomenology.
