Abstract

• 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 0^o, 15^o, and 30^o 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
