Scanning of the Intermodulation of Superconductor Resonators Research Advisor: Dr. Stephen Remillard At the resonant frequency, superconductor resonators produce intermodulation distortions, smaller signals near the resonant frequency. By inducing external microwave signals, it is possible to analyse the patterns of intermodulation distortions (IMD) in several different types of superconductor resonators. These measurements can be used […]

Spectroscopic Emission from Argon and Nitrogen Microplasmas Research Advisor: Dr. Stephen Remillard Many electronics utilize microgaps, and these electronics can produce plasma, whether intended or not, if it was not intended this plasma can damage the electronics. The breakdown condition and spectral emission of nitrogen and argon plasmas were examined in a microgap under microwave […]

Evidence for Distinct Sources of Superconducting Nonlinearity Research Advisor: Dr. Stephen Remillard The nonlinear response of cuprate superconducting devices present technological hurdles and scientific opportunities.  Intermodulation Distortion (IMD) generated by the nonlinear response is usually undesirable in superconducting devices, however, some devices leverage IMD to their advantage.  By analyzing the magnetic relaxation of IMD in […]

Inductive and Resistive Nonlinearities of a Superconductor Resonator Research Advisor: Dr. Stephen Remillard This experiment is designed to compare the feedback from an altered superconductor resonator with a conventional, unaltered superconductor resonator. Superconducting transmission lines are patterned on a lanthanum aluminium substrate chip with a geometry that resonates within the microwave range. Nonlinearities, distortion of […]
