Cryogenic Current Comparator Measurements at 77 K Using Thallium-2223 Thick-film Shields
Published
Author(s)
Randolph E. Elmquist
Abstract
This paper describes resistance ratio measurements using cryogenic current comparator (CCC) devices that operate at 77 K. The magnetic shields are Thallium-based thick films on MgO substrates. The effectiveness of three shield geometries is determined using one-to-one and ten-to-one winding ratios.
