Abstract

The Electron Emission Test (EET) chamber in the Utah State University Materials Physics Group (MPG) is used to determine the electron yield of highly insulating materials. An electrometer is employed alongside the EET chamber to measure the output current of 10-6 to 10-14 pulses of 10-7 seconds to DC duration. In previous years, a first- generation electrometer was used for these measurements. However, the introduction of a new electrometer presents an opportunity to achieve faster measurement speeds and improved sensitivity to smaller current values.
