Email address M Khademi@ph iut ac ir D of submission April 20 2010 Date Department of Physics Isfahan University of Technology Isfahan 84156 83111 Iran ersity I Degree M Sc Language Persian rsian Supervisor Assoc Prof A A Babaei Brojeni Email brojeni@cc iut ac ir iut ac ir Abstract At the present time Superconducting power cables have been of considerable interest since onducting derable the discovery of the high Tc superconducting materials and many investigations have been stigations carried out on the HTSC single crystals and due to the vast varieties of potential applications gle otential thin film of these materials are practically useful and hence have been studied by several n researches But there has always been an important attempt for the researchers particularly for ays b hers the experimentalist to somehow reduce the ac losses in the material One way could be how twisting the sample Here we would like to check if we can reduce the ac losses in a thin type superconductors HTSC Bases on the domain of validity of the critical state model CSM ases A new and straightforward calculation is made of the loss in a very thin superconducting strip lculation uperconducting of rectangular cross section e g the coating on a coated superconductor carrying ac transport e g carr current in applied magnetic field We have shown in this thesis that by passing a transport field current in a certain direction through a thin HTSC it is possible to reduce the ac losses in uce these HTSC configuration W have also compared the result of our numerical calculations We merical by solving a couple of self consistent equations done on a current carrying thin HTSC tape ying being in a perpendicular external magnetic field with the result from the case that the sample rnal carries no transport current The comparison clearly shows the ac losses reduction T eduction Keywords
