Iterative design procedure for optimum placement of vapor deposited Nb-Sn ribbon superconductors in high field large bore modular magnets
Superconducting Nb-Sn intermetallic compound synthesis from elemental powders by converging shock waves
A new type of ether drift experiment searches for anomalous torques on a permanent magnet. A torsion pendulum is used at liquid helium temperature, so that superconducting cylinders can be used to shield magnetic fields. Lead shields attenuate the earth's field, while Nb-Sn shields fastened to the pendulum contain the fields of the magnet. The paper describes the technique by which the earth's field can be reduced below 0.0001 G while simultaneously the moment of the magnet can be reduced by a factor 7 x 10 to the 4th.
