Construction of two computer controlled experiments to measure the resistivity R-T and the critical I-V

In this work, two computer controlled experiments to measure the resistivity (R-T) and the critical current (I-V) were constructed. The sample holder for the resistivity measurement experiment was improved in order to hold large samples whose diameters are in the order of 1 cm long. The sample holder of the I-V experiment was also improved to allow the Ic measurement with no need to solder the wires on the tape. The computer controlled data acquisition enabled us to do more readings with smaller time intervals compared with the manual method. (author)
