Novel High-Current SRF Cavity With On-Cell Waveguide Dampers

A new concept was proposed to improve the Higher-Order-Mode (HOM) damping in Superconducting Radio Frequency (SRF) cavities beyond state-of-the-art. A prototype cavity was planned to be built and tested in JLab’s Vertical Test Area as a proof-of-principle.

Simple coplanar waveguide resonator mask targeting metal-substrate interface

This white paper presents a single-layer mask, found at https://github.com/Boulder-Cryogenic-Quantum-Testbed/simple-resonator-mask. It is designed for fabrication of superconducting microwave resonators towards 1:1 comparisons of dielectric losses from the metal-substrate interface. Finite-element electromagnetic simulations are used to determine participation ratios of the four major regions of the on-chip devices, as well as to confirm lack of crosstalk between neighboring devices and demonstrate coupling tunability over three orders of magnitude. This mask is intended as an open-source community resource for facilitating precise and accurate comparisons of materials in the single-photon, millikelvin regime.
