Our magnet got to 44 Tesla early this morning, a success as we recorded ALOT of good data. Here is a picture of just some of the equipment we use to monitor more than 30 voltages, temperatures, and magnetic fields during the experiment—applying this knowledge to our next magnet!

We are wrapping our first magnet to attempt 60 Tesla! Hoping for success, yet planning for three attempts (different coils) in next 2 months to increase likelihood we will reach 60 Tesla. These magnets are small. These magnets are powerful. ⁦@ResonTech⁩ ⁦@ETH

Our COO @SchoenzartJas just presented our magnet technology at the Rocky Mountain NMR Symposium. She’s able to bring our magnet to the talk and hold it in her hand. Go Miniature! #NMR

SUPER conductors can carry an incredibly high electrical current without heating, NORMAL conductors (ex, Copper) don’t. So to charge our magnets to >40 Tesla we use ALOT of copper in the leads to bring >1000 Amperes to the cryostat, see black thick cables.

We have joined X! We want to keep you updated about our technology updates and everything else going on at ResonX. Below see a quench at 46.5 Tesla! Aiming for 100 Tesla.. #NMR #Magnets
Alexander Barnes@MagnetXander

Quench at 46.5 Tesla. It took us 5 days to make this magnet, and 4 days to charge to full field. We expect many more such experiments next year— move fast, learn fast. Targeting high (enough) resolution NMR >60 Tesla next year.

We are building next-gen instruments for magnetic resonance—small but powerful magnets, better gyrotrons, RF, and novel approaches to MAS. But we aren’t in this alone— only with our community together will NMR and EPR prosper. @ResonTech @ETH @SchoenzartJas #GlobalnmrOC2024

New preprint available from @AMPERE_MR: Which motional time scales lead to residual dipolar couplings under MAS? Do they depend on the MAS frequency, experiments, rf-field amplitudes, or coupling strength? Investigated by PhD student Kathrin Aebischer in doi.org/10.5194/mr-202…
