THE DIMINISHING METHOD OF MAGNETIC FIELD EFFECT DUE TO CURRENT LEAD WIRE DURING SUPPLYING CURRENT TO SAMPLE INSIDE CRYOSTAT AND SUPERCONDUCTIVE CHARACTERISTIC CALIBRATE APPARATUS

摘要

The present invention is a magnetic field by the current leads in a low temperature vessel to, minimize the influence of the magnetic field derived by means of the current leads By connecting such symmetry is maintained as a whole with respect to the current lead-in and measuring the output line sample is introduced into the low temperature vessel It provides a method and minimize influence superconductivity measurement unit. The invention to be symmetrical from side to side along a first input current leads and the longitudinal direction inside the second input current leads the measurement space drawn out of the positive (+) current input terminal connected to the power source in the measuring space of the low temperature vessel for this purpose extends commonly connected again in the lower part of the measuring space is, the measurement samples are the first and second input current hagoseo location centered between symmetrical arrangement of the leads, and one terminal is commonly connected to the lead-in first and second input current, connected with the site, and the other terminal is connected to the anode power source - is characterized by being a process in which the output connection of the current line and the current output terminal.
