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.
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.
