LCLS-II-HE verification cryomodule high gradient performance and quench behavior
S. Posen, A. Cravatta, M. Checchin +43
An 8-cavity, 1.3 GHz, LCLS-II-HE cryomodule was assembled and tested at Fermilab to verify performance before the start of production. Its cavities were processed with a novel nitr…
TOF-SIMS Analysis of Decoherence Sources in Nb Superconducting Resonators
Akshay A. Murthy, Jae-Yel Lee, Cameron Kopas +6
Superconducting qubits have emerged as a potentially foundational platform technology for addressing complex computational problems deemed intractable with classical computing. Des…
Measurement of the Low-temperature Loss Tangent of High-resistivity Silicon with a High Q-factor Superconducting Resonator
Mattia Checchin, Daniil Frolov, Andrei Lunin +2
In this letter, we present the direct loss tangent measurement of a high-resistivity intrinsic (100) silicon wafer in the temperature range from ~ 70 mK to 1 K, approaching the qua…
Signatures of Enhanced Superconducting Properties in Niobium Cavities
D. Bafia, A. Grassellino, M. Checchin +2
Superconducting radio-frequency (SRF) niobium cavities are critical for modern particle accelerators, as well as for advancing superconducting quantum systems and enabling ultra-se…
