Summary

The approaches to HTSC modeling according to their defects have been examined. A computer modeling of the quality of HTSC superconducting properties with the aim to obtain data on the permissible parameters of the crystal defects disposition, which guarantee the critical current, was carried out. The obtained data can be used to manage the process in order to produce a superconductor with a guaranteed quality of its superconducting properties. As a result of the experiment the sum areas of defects at which a superconducting cluster is formed, were estimated. The maximum total area of defects when superconductivity was formed is 80%. When a superconducting cluster was formed the area of defects was at the average 40%. The authors compared the influence of horizontal and vertical defects on the superconductor quality. During the experiment the maximal number of horizontal defects when the superconductivity was formed, was 270849, the maximal number of vertical defects was 367642. The number of horizontal defects influences more on the cluster formation. The conclusions are the following: the sum area of defects observed of the HTSC material is admitted to 40%; at technological processing it should be taken into account that the material may be stretched out but not twist.
