“…The outsert consists of an 18layer Nb 3 Sn coil and a 32 double-pancake NbTi coil. It is 'quasi-adiabatic', unlike the earlier hybrids at MIT, which were cryostable [72]. The inserts were designed and built by Weggel using both Cu-Be monohelix technology and the new Cu-Ag sheet metal in a radially-cooled Bitter technology.…”

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.

“…On the other hand, virtually all non-MRI/NMR, research-purpose superconducting magnets for fields as high as 15 T ( 640 MHz) marketed are dry. A hybrid magnet, for example, a research-purpose high-field magnet that generates fields in the 30-45 T range; have a high-power (10-24 MW) water-cooled magnet (20-34 T) placed in the room temperature bore of a superconducting magnet (10-15 T), which is always immersed in liquid helium [1], [2]. Ideally, the superconducting part of any hybrid should be dry, because the high-power water-cooled magnet frequently fails, forcing the loss of the entire volume of liquid helium in the cryostat.…”

We report here on the status of our program aimed to build and operate a dry MRI magnet. The system incorporates a new design/operational concept that we believe it will be eventually adopted by manufacturers of the next generation of superconducting magnets. System features include: a) liquid free; b) if required by the user, cryocooler microphonics free over a period of time; c) ability to maintain a constant operating field over a specified period of time, even in the event of a power outage or during cryocooler maintenance. The basis of this new design/operation concept, among other features, is the presence of solid cryogen, solid neon for this system, in the cold body that also contains the magnet to enhance significantly the cold body's heat capacity. Details of the system design-magnetic and cryogenics are presented in this paper.
