Superconductors in NMR spectrometers

NMR resolution scales with field, and structural biology has spent fifty years buying resolution by buying tesla. The highest-field spectrometers pass the point where niobium-titanium has anything left, so the inner coils are niobium-tin and, at the very top, high-temperature conductor. This is the application that pulls a new conductor into production before anyone else can afford it. That makes it a useful leading indicator for the magnet industry as a whole.

What is stopping NMR spectrometers

Homogeneity and drift, held to an extraordinary tolerance in a magnet that is never switched off. A conductor that satisfies that needs joints good enough to persist for years, which is a far stricter requirement than carrying the current in the first place, and it is one of the reasons high-temperature conductors have been slow to arrive here.

What a better material would change for NMR spectrometers

Every jump in field here has come from a new conductor rather than a better magnet design, and the next one will be the same. A high-temperature conductor with joints good enough to run persistent would move the ceiling again, and structural biology would spend it the week it arrived.
