44. Novel Aluminum-based High-Q Cold RF Resonators for ADMX

Katsuya Yonehara (Fermilab)

26/08/2015, 14:45

Improved aluminum refining techniques now provide high-quality, cost-effective high-purity aluminum samples. The high-purity aluminum will be better resonator material than copper because of its extremely low resistivity and high thermal conductivity at cryogenic temperature in strong magnetic fields. We will show material properties of high-purity aluminum and demonstrate possible improvement...

80. Primer on Superconducting Radiofrequency Cavities

Daniel Bowring (Fermilab)

26/08/2015, 15:15

This overview will outline the motivation and concepts behind superconducting radio-frequency microwave cavities, primarily in the context of accelerator cavities.

68. Magnetic Field Limits of SRF Cavities

Sam Posen (Fermilab)

26/08/2015, 15:45

This talk will discuss the ultimate limitations for high Q0 operation of SRF cavities, including theoretical predictions and experimental measurements. Various SRF materials are considered and realistic expectations for maximum magnetic fields on the walls of the cavity are presented.

61. An RF sputtering system for thin film superconducting cavity R&D

Maria Simanovskaia (UC Berkeley)

26/08/2015, 16:15

Here we will outline an RF sputtering system that has recently been installed at UC Berkeley with the goal of developing superconducting thin film cavities for axion searches.
