Impact of Forming, Welding, and Electropolishing on Pitting and the Surface Finish of SRF Cavity Niobium
Lance D. Cooley,D. Burk,C. Cooper,N. Dhanaraj,M.H.Foley,D Ford,K Gould,D. Hicks,Roman Novitski,Alexander Romanenko,R. Schuessler,C. Thompson,Genfa Wu +12 more
TL;DR: In this article, a broad range of coupon electropolishing experiments are described to ascertain the mechanism(s) by which large defects are formed near superconducting radio-frequency (SRF) cavity welds.
Journal ArticleDOI
Challenges and Design of the Transport Solenoid for the Mu2e Experiment at Fermilab
Giorgio Ambrosio,N. Andreev,Sergey Cheban,R. Coleman,N. Dhanaraj,D. Evbota,Sandor Feher,V.V. Kashikhin,M.J. Lamm,V. Lombardo,M. L. Lopes,J. P. Miller,Thomas H. Nicol,D.F. Orris,T. Page,T.J. Peterson,Vitaly Pronskikh,W. Schappert,M.A. Tartaglia,R. Wands +19 more
TL;DR: In this article, the conceptual design of the Transport Solenoid is presented and discussed focusing on coupling issues and the proposed solutions, and the quench protection system should handle all possible quench and failure scenarios in all three solenoids.
ReportDOI
Physical Properties of Niobium and Specifications for Fabrication of Superconducting Cavities
C. Antoine,M.H.Foley,N. Dhanaraj +2 more
TL;DR: In this article, the significance of the important mechanical properties used to characterize niobium and to present the optimal range of values is reviewed, and the importance of these properties is discussed.
Journal ArticleDOI
Reference Design of the Mu2e Detector Solenoid
Sandor Feher,N. Andreev,J. Brandt,Sergey Cheban,R. Coleman,N. Dhanaraj,I. Fang,M.J. Lamm,V. Lombardo,M. L. Lopes,J. P. Miller,R. Ostojic,D.F. Orris,T. Page,T. Peterson,Z. Tang,R. Wands +16 more
TL;DR: The reference design of the detector solenoid is summarized in this article, where the authors present detailed design specifications that are sufficient for vendors to produce the final design drawings, tooling and fabrication procedures and proceed to production.
Proceedings ArticleDOI
3.9 GHZ superconducting accelerating 9-cell cavity vertical test results
T.N.Khabiboulline,C. Cooper,N. Dhanaraj,H. Edwards,M.H.Foley,E. Harms,D. Mitchell,Allan Rowe,Nikolay Solyak,W.-D. Moeller +9 more
TL;DR: In this paper, the 3.9 GHz accelerating cavity was proposed to improve the beam performance of the FLASH (TTF/DESY) facility, and the first 9-cell Nb cavities were tested in a vertical setup and they didn't reach the designed accelerating gradient.
