Reduced-size prototype coils for the 32 T all-superconducting magnet have been successfully tested. The results include the generation of 27 T, which is a record for superconducting magnets.
On the road toward a groundbreaking all-superconducting magnet, the MagLab successfully tests a prototype that is already in the record books.
An overpressure furnace capable of developing high current density in significant-sized coils (up to 15 cm diameter and 50 cm long) has been brought into commission. The furnace is enabling reaction of solenoids made out of Bi-2212 destined for tests of NMR quality magnets at proton frequencies greater than 1 GHz.
Are electrons stronger in pairs? MagLab physicists released new research published in Nature Communications that could help answer a looming question about the strength of Cooper pairs in high temperature superconducting materials.
Grain boundaries in BaFe2As2 (122), which is an iron-based superconductor, block current flow. This study, which was a collaboration with a group at Northwestern University, used a Local Electrode Atom Probe (LEAP), which is a relatively new experimental tool, to make a 3-D atom-by-atom reconstruction of a region of a 122 sample that included a grain boundary. The data showed that the chemical composition varied across the grain boundary and in that oxygen was present at the grain boundaries. These variations in composition may contribute to grain boundary's reduced current carrying capacity.
New process fosters development of high field magnets and new high-energy particle accelerators.
Oxford Instruments has named MagLab physicist Chiara Tarantini the 2014 winner of its Lee Osheroff Richardson North American Science Prize.
The MagLab has successfully completed construction of the cold-mass of a series-connected hybrid magnet for the Helmholtz-Zentrum Berlin.
Scientists have developed a new way to test tape made of the promising high-temperature superconductor YBCO, a key step toward building stronger superconducting magnets.
MagLab scientists developed a method to process high-temperature superconducting Bi-2122 round wire that significantly boosts its ability to carry large electrical currents and generate high magnetic fields.
