Transmutation Sciences Materials (TRP)
• A Secondary Electron Emission test stand has been designed to study the initial conditions of secondary electrons emitted from niobium in cryogenic state.
• Secondary electron particle distributions have been studied for 0o, 15o, and 30o beveled surfaces
• BCP and EP samples have been compared showing that the EP count is over twice as large as the BCP count
• Electron beam surface conditioning was examined. Conditioning appears to be sensitive to pulse duration and the number of impacts
• Good comparison have been shown between experiment and simulation
