Cryogenic RF characterization of the MAGO cavity for high-frequency gravitational-wave detection
Can Dokuyucu, Bianca Giaccone, Tom Krokotsch +13
Superconducting radio-frequency (SRF) cavities are promising resonant sensors for gravitational-wave detection in the kHz-MHz frequency range. We report the cryogenic RF characteri…
Latest Development of Electropolishing Optimization for 650 MHz Niobium Cavity
V. Chouhan, D. Bice, D. Burk +15
Electropolishing (EP) of 1.3 GHz niobium superconducting RF cavities is conducted to achieve a desired smooth and contaminant-free surface that yields good RF performance. Achievin…
Visual, Optical and Replica Inspections: Surface Preparation of 650 MHz NB Cavity for PIP-II Linac
V. Chouhan, D. Bice, D. Burk +2
Surface preparation of niobium superconducting RF cavities is a critical step for achieving good RF performance under the superconducting state. Surface defect, roughness, and cont…
Study on Electropolishing Conditions for 650 MHz Niobium SRF Cavity
V. Chouhan, D. Bice, F. Furuta +8
The PIP II linear accelerator includes different types of niobium SRF cavities including 650 MHz elliptical low (0.61) and high (0.92) beta cavities. The elliptical cavity surface…
Effect of Electropolishing on Nitrogen Doped and Undoped Niobium Surfaces
V. Chouhan, F. Furuta, M. Martinello +2
Cold electropolishing (EP) of a nitrogen-doped (N-doped) niobium (Nb) superconducting RF (SRF) cavity was found to improve its quality factor. In order to understand the effect of…
