Superconducting magnetic shields

    Our proposed composite combined magnetic shield has cylinder fragments made of high-temperature superconductive material. The volume of a single fragment is 0,8 см3

 Shielding factor of k = 300 for a single fragment at magnetic frequency field 10 кHz. Shielding factor k = 400 is for two and more fragments together at the same frequency.

Magnetic shield of two segmentsMagnetic shield of three segments

   It is possible to produce ceramic cylinders  with thickness of about 30 mm and diameter of about 80 mm, which enlarges the shielding volume to 16,5 cm3.
