“…The maximum solenoidal field is higher (31 T) than in the previous example, but the bore can be smaller ͑6 , r , 8 cm͒. Several hybrid magnets with at least this field have operated for many years [163]. More recent magnets are of even higher field.…”

The status of the research on muon colliders is discussed and plans are outlined for future theoretical and experimental studies. Besides work on the parameters of a 3-4 and 0.5 TeV center-of-mass (COM) energy collider, many studies are now concentrating on a machine near 0.1 TeV (COM) that could be a factory for the s-channel production of Higgs particles. We discuss the research on the various components in such muon colliders, starting from the proton accelerator needed to generate pions from 1098-4402͞99͞2(8)͞081001(73)$15.00 © 1999 The American Physical Society 081001-1 PRST-AB 2 CHARLES M.

“…One is to restrain the coils by a stiff, strong structure [16]. The other is to allow the coils to move, thus reducing the large force [17]. The first option requires a substantial structure inside the resistive magnet housing that can be complicated to design, adds to the cost and may reduce the field.…”

Resistive magnet technology for hybrid inserts

The world’s highest-field dc magnets have, for roughly the past thirty years, consisted of resistive-superconducting hybrid magnets. These magnets use superconducting technology for the outer coils, where the magnetic field is moderate, and resistive-magnet technology for the inner coils, where the field is highest. In such a configuration, higher fields are attained than is possible with purely superconducting magnet technology, and lower lifetime (capital and operating) costs are attained than with a purely resistive magnet. The resistive coils of these magnets represent the pinnacle of high-field resistive-magnet technology and have been the focus of much of the resistive magnet technology development over the past thirty years. The evolution of high-field resistive magnet technology is presented, focusing on the development of hybrid inserts.

“…la), est insignifiant; quant à l'investissement nécessaire à sa réalisation, il est au moins d'un ordre de grandeur inférieur au prix de construction d'un champ continu intense dont le coût de fonctionnement, en outre, est très important. D'où l'intérêt des champs pulsés crowbar quasistatiques ; ce d'autant plus que les champs réalisés avec cette technique dépassent largement les 30 T du champ continu actuellement le plus intense [3], Fig. 1 a.…”

2014 Un champ pulsé est défini par le champ crête B0, l'énergie magnétique W et le rayon intérieur a1 des bobines. Nous proposons un ensemble de formules qui, pour chaque couple w = W/2,5 a31 B20 et 0393 = diamètre extérieur/longueur des bobines, donnent : l'« épaisseur » de chaque bobine, leur constante de temps, l'homogénéïté du champ magnétique, la température du bobinage à la fin d'une impulsion crowbar. Nous montrons, que pour chaque champ pulsé, c'est dans la bobine 0393 = 1,36, que les contraintes magnétiques de coeur sont minimales. Nous analysons le rendement magnétique en prenant en compte l'échauffement adiabatique du bobinage. A chaque étape du texte, apparaît l'intérêt des bobines très épaisses.Abstract. 2014 A pulsed magnetic field is characterized by the peak value B0, by the magnetic energy W and by the inner coil radius a1.
