ABSTRACT
Continued advances in nanostructured materials have made it necessary to develop materials with specific thermoelectric properties. The 3ω Method provides an accurate measurement of one such property, thermal conductivity. It will be used in this research to find high electrical conductivity alloys with low thermal conductivity.

The objective of this project is to study the properties of secondary electron emission from niobium samples, cleaned at the Los Alamos National Laboratory, at cryogenic temperatures to enhance existing multipacting codes with data on the samples. The predominant cause of power loss in radio-frequency superconducting accelerators cavities is multipacting. This project studies the secondary electron distribution from niobium metal due to incident primary electrons. The experiments on the niobium sample are performed in an environment close to that present in a superconducting accelerator cavity.
The experiment is performed in a vacuum chamber capable of achieving ultra high vacuum levels …
