摘要：
A device for measuring the critical current of superconductors by means of pulse current is described. Due to decrease in the heat amount releasing at the current contacts, the accuracy of measurements is enhanced, and a possibility appears to measure the 'tail' of the superconducting transition and to determine the intergranular and intragranular current on the basis of the data obtained. The block diagram of the device and the schematic of one of its units are given.
