Abstract | The reliable fabrication of robust, uniform, long length silver-sheathed Bi-2223 superconductor tapes capable of carrying high current densities represents a key factor towards the development of windings to be integrated in electric power devices. Bi-2223 tapes to be used for the fabrication of coils with a silver alloy sheath having 19 and 55 filaments in unit length of 100 meters have been fabricated by the Powder-In-Tube method. The critical current density enhancement of Bi-2223 tapes by means of the optimisation of mechanical deformation and thermal treatment parameters is here presented. The realised Bi-2223 tapes have been deeply characterised by DC and AC measurements at different temperatures. To evaluate the capabilities of the multifilamentary tapes in the realisation of coils their electrical behaviour as a function of magnetic field and bending strain has been investigated. |

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.
