“…The Energy Doubler magnets were designed assuming the conductor could be placed accurately enough ( � 1 mil) (8) to give high field multipoles a few times 10-4 at a reference radius of one inch. Generally speaking the measured values meet those expectations (11)(12)(13). An important feature of the magnet is the ability to null the normal and skew quadrupole moments by off-centering the collared coil in the external iron with the suspension cartridges.…”

“…The second path is more difficult since it hits several physical limits: (i) the protection constraints for long magnets, where the energy has to be absorbed by the coil enthalpy, (ii) the strain on the conductor induced by electromagnetic forces, (iii) instabilities related to the self-field and to the magnetization. Magnets in previous particle accelerators [17][18][19][20] operated with a current density in the strand (the so-called engineering current density jeng) between 500 and 600 A/mm 2 , and coil width in the range of 10 to 30 mm (see Fig. 1).…”

The HL-LHC project aims at allowing to increase the collisions in the Large Hadron Collider by a factor ten in the decade 2025-2035. One essential element are the superconducting magnets around the interaction region points, where large aperture magnets will be installed to allow to further reduce the beam size in the interaction point. The core of this upgrade is the Nb3Sn triplet, made of 150 mm aperture quadrupoles of in the range of 7-8 m. The project is being shared between CERN and US Accelerator Upgrade Program, based on the same design, and on two strand technologies. The project is ending the short model phase, and entering the prototype construction. We will report on the main results of the short model program, including quench performance and field quality. A second important element is the 11 T dipole that replacing a standard dipole makes space for additional collimators. The magnet is also ending the model development and entering the prototype phase. A critical point in the design of this magnet is the large current density, allowing increasing the field from 8 to 11 T with the same coil cross-section as in the LHC dipoles. This is also the first two-in-one Nb3Sn magnet developed so far. We will report the main results on the test and the critical aspects.

“…Thus the first term that comes into the expansion is the 14 th pole that varies like x 7 and evaluation of this term shows that it is negligibly small over the inner 2/3 of the aperture. Table 2 gives the rms values measured for the 870 dipoles initially installed in the Tevatron [10,11]. The data on the quadrupoles is available in Ref.…”

Superconducting magnets have played a key role in advancing the energy reach of proton synchrotrons and enabling them to play a major role in defining the Standard Model. The problems encountered and solved at the Tevatron are described and used as an introduction to the many challenges posed by the use of this technology. The LHC is being prepared to answer the many questions beyond the Standard Model and in itself is at the cutting edge of technology. A description of its magnets and their properties is given to illustrate the advances that have been made in the use of superconducting magnets over the past 30 years.
