The MagLab has successfully completed construction of the cold-mass of a series-connected hybrid magnet for the Helmholtz-Zentrum Berlin.
This high-tech spool is one big bobbin.
A prototype high-temperature superconducting coil for the 32 T all-superconducting magnet was constructed with YBCO tape and successfully tested in the large-bore resistive magnet at the MagLab.
MagLab engineers are building two cable-in-conduit superconducting coils for hybrid magnets, each with a resistive inner coil and a superconducting outer coil.
First direct evidence that filament fracture accompanies degradation of superconducting cables designed for the International Thermonuclear Experimental Reactor (ITER). The tokomak fusion reactor, now under construction in France, is an international collaboration crucial to future energy generation from nuclear fusion.
Two scientists put their heads together and created a machine that speeds along magnet production.
Ferro-pnictide superconductors attracted immediate attention for potential applications due to their high superconducting transition temperatures (Tc up to 56 K) and high upper critical magnetic fields (Hc2 over 100 T). Unfortunately, much as in cuprates, grain boundaries (GBs) were found to obstruct their current carrying capability. This posed a serious technological problem because wires for magnets cannot be single crystals and, thus, inevitably contain grain boundaries. This work shows that low-temperature synthesis of the compound (Ba0.6K0.4)Fe2As2 (Ba-122) in the form of polycrystalline wire achieves a current density three times that of state-of-the-art Nb3Sn wires.
A magnet maker joins an international experiment that could change the world.
Like most people, we'd rather pay less for electricity. Which is one reason (though not the only one) that we use and build superconducting magnets.
