Abstract | Progress in developing long-length YBCO coated conductors (CC) with high critical currents, up to almost 500 A per cm-width, is reported. Coated tapes based on commercial quality stainless steel substrates are manufactured employing a HR-PLD-YBCO together with an IBAD-YSZ processing route (HR-PLD: high-rate pulse laser deposition, IBAD: ion-beam assisted deposition). At 77 K in self field, critical currents up to 495 A per cm tape width were achieved in 4-10 mm wide and 5-9 m long tapes. With a 0.1 mm thick substrate tape employed for CC manufacturing, the engineering current density achieved corresponds to 494 A/mm/sup 2/. At 4.2 K and a parallel magnetic field of 23.5 T, a critical current of typically 1,350 A per cm width was observed. Study of mechanical properties of the coated tapes revealed their outstanding performance under bending and axial stress. Influence of thick shunt layers on the performance of the coated conductor was studied. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
