Undergraduate electrical engineering students are developing material-processing techniques to fabricate titanium nitride thin films with high kinetic inductance and minimal loss at low temperatures. The students are developing the necessary deposition recipes and will test the thin films at low temperatures. The results of this project will contribute to novel designs of high-gain, low-noise amplifiers for quantum computing applications and new types of electrical current standards.
Another team of undergraduate students in the Engineering Department at UMass Boston is tasked with designing a sample holder and associated electronics for controlling the orientation and handling of a niobium sample during the experiment. Accurate measurement of secondary electron emission in scientific experiments provides better insight into plasma properties. Understanding how the sample angle affects secondary electron emission is vital to the progress of particle accelerator science research.
