Abstract :
Investigation are continuing on a cryogenic current comparator (CCC) having the shield made by an extended thick film of the YBCO high-temperature superconductor (HTS). Recent results relate to the adopted open-toroidal open-tube geometry are reported, regarding both error ratio attenuation measurements and numerical treatment of a mathematical model.
