WEPMF018	Magnet Designs for the eRHIC Rapid Cycling Synchrotron	dipole, quadrupole, sextupole, synchrotron	2404
	H. Witte, I. Marneris, V.H. Ranjbar BNL, Upton, Long Island, New York, USA
	Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-AC02-98CH10886 with the U.S. Department of Energy. Presently the electron-ion collider eRHIC is under design, which aims to provide a facility with a peak luminosity of 10³⁴cm^-2sec^-1. Part of the eRHIC design is a rapid cycling synchrotron, which accelerates electrons from 1-18 GeV. In this paper we present conceptual designs of the required dipole, quadrupole and sextupole magnets. The magnets meet the specifications in terms of performance and field quality with an acceptable power dissipation. The power supply requirements are also discussed.

WEPMF072	Magnet Power Supplies for ALS-U	power-supply, storage-ring, dipole, sextupole	2538
	G.C. Pappas, J.-Y. Jung, C.A. Swenson LBNL, Berkeley, California, USA
	The ALS-U project is an upgrade to the existing Advanced Light Source at Lawrence Berkeley Laboratory to a diffraction limited light source. To be able to achieve the small horizontal emittance of the ALS-U, the three bend achromats in the ALS will be replaced with nine bend achromats. Because the lifetime of the ALS-U beam will be significantly reduced, the plan is to use a swap out injection scheme between the storage ring and a new accumulator ring. The present plan is to use individual power supplies for each magnet in the storage ring, and series connected magnet strings for the accumulator ring. The sheer number of supplies needed, along with the tighter stability requirements for the ALS-U, is demanding in terms of the power supply requirements for stability and reliability. This paper will discuss the ALS-U magnet power supply requirements, and possible options to meet them.

WEPML026	Large-Aperture High-Field Nb3Sn Dipole Magnets	dipole, collider, luminosity, operation	2738
	A.V. Zlobin, V.V. Kashikhin, I. Novitski Fermilab, Batavia, Illinois, USA
	Funding: Work is supported by Fermi Research Alliance, LLC, under contract No. DE-AC02-07CH11359 with the U.S. Department of Energy Large-aperture high-field dipole magnets based on Nb3Sn superconductor are necessary for various accelerator systems of future hadron and muon colliders. In hadron colliders, they are used needed for beam separation before and after interaction points. In a muon collider, they are considered for both the arc and the interaction regions to provide room for internal absorbers protecting magnets from the muon decay products. These magnets can also be used in test facilities to produce a background magnetic field for testing conductor samples or insert coils. High level of magnetic field and large aperture size lead to large Lorentz forces and mechanical strains and stresses which can damage brittle Nb3Sn coils. This paper describes conceptual designs of 120-mm aperture dipoles with magnetic fields up to 15 T based on cos-theta coils. Stress management technique and magnet parameters are also presented and discussed.

WEPML027	Conceptual Design of a 17 T Nb3Sn Accelerator Dipole Magnet	dipole, collider, luminosity, quadrupole	2742
	A.V. Zlobin, J.R. Carmichael, V.V. Kashikhin, I. Novitski Fermilab, Batavia, Illinois, USA
	Funding: Work is supported by Fermi Research Alliance, LLC, under contract No. DE-AC02-07CH11359 with the U.S. Department of Energy Nb3Sn dipole magnets with a nominal field of 16 T and sufficient operation margins are being considered for the LHC energy upgrade or a future Very High Energy Hadron Collider. Magnet design studies are being performed in the framework of the US Magnet Development Program to explore the limits of the Nb3Sn accelerator magnet technology and feasibility of such magnets, as well as to optimize the magnet design, performance parameters and cost. This paper describes the conceptual design of a 17 T dipole magnet with 60 mm aperture and 4-layer cos-theta coil being developed at Fermilab. The results of magnetic and mechanical analyses, including the non-linear effects in magnetic field and the possible stress management techniques, are also presented and discussed.
