Journal ArticleDOI
Time variations of fields in superconducting magnets and their effects on accelerators
D.A. Herrup,M.J. Syphers,D.E. Johnson,R.P. Johnson,A.V. Tollestrup,R.W. Hanft,B.C. Brown,M.J. Lamm,M. Kuchnir,A.D. McInturff +9 more
TL;DR: The time dependence of magnetic fields in the superconducting magnets of the Fermilab Tevatron is discussed in this paper, where it is shown that small but important changes in the magnetic fields occur with (ln t) time dependencies.
Proceedings ArticleDOI
About the mechanics of SSC dipole magnet prototypes
A. Devred,T. Bush,R. Coombes,J. DiMarco,C. Goodzeit,J. Kuzminski,M. Puglisi,P. Radusewicz,P. Sanger,R. Schermer,G. Spigo,J. Thompkins,J. Turner,Z. Wolf,Y. Yu,H. Zheng,T. Ogitsu,Michael Anerella,J.G.

TL;DR: In this article, the authors analyzed the magnetic properties of the SSC main-ring dipole magnet during cooldown and excitation and found that the magnetic behavior is sensitive to the collar-yoke interference and that the magnets exhibit somewhat erratic changes in coil endloading during cooldown.
Proceedings ArticleDOI
A high field hts solenoid for muon cooling
S.A. Kahn,M. Alsharo'a,Rolland Johnson,M. Kuchnir,Ramesh Gupta,Robert B. Palmer,E. H. Willen,D. J. Summers +7 more
TL;DR: In this article, the authors describe a conceptual design of a 45 Tesla solenoid based on Bi-2223 HTS tape, where the magnet will be operated at 4.2 K to take advantage of the high current carrying capacity at that temperature.
Journal ArticleDOI
Tests of full scale SSC R&D dipole magnets
James Strait,B.C. Brown,R.W. Hanft,M. Kuchnir,M.J. Lamm,R. Lundy,Paul M. Mantsch,P.O. Mazur,A.D. McInturff,J.R. Orr,J.G. Cottingham,P. Dahl,G. Ganetis,M. Gerber,A.K. Ghosh,C. Goodzeit,A. Greene,J.

Scanlan,C. Taylor,J. Zbasnik,M. Chapman,A. Devred,J. Kaugerts,J. Peoples,J. C. Tompkins,R. Schermer +42 more
TL;DR: In this paper, four full-scale SSC (Superconducting Super Collider) research and development dipole magnets, incorporating successive mechanical design improvements, have been quench-tested and three of the magnets are heavily instrumented with sensors to measure their mechanical behavior and verify the effectiveness of the mechanical improvements.

TL;DR: In this article, the quench propagation velocity on the turn where quench occurs is calculated and verified by reiterating the analysis on adjacent turns, and the velocity value appears to be higher than previously measured.
