Abstract: We report on a recent experimental setup for the investigation of the relaxation rate of the persistent current in an assembly of closed superconducting loops made out of currently manufactured coated conductors. This report describes how to prepare closed superconducting loops made with commercial coated conductors for the assembly, mount the assembly in a cryostat, and operate the experimental setup for data acquisition. This documentation is intended to support future investigations of coated conductors in either tape or wire form or for bulk superconductors in an appropriate form of closed circuit. One of the advantages of this experimental setup is the ability to study superconducting current characteristics at cryo-temperatures in magnetic field at time scale of seconds to hours.
