| Abstract | Superconducting helicoids, i.e., magnets with planar turns, are in the process of being developed. Their main advantages are: high mechanical rigidity, the possibility of current redistribution across the turn width in accordance with magnetic field value, and the possibility of utilizing superconductors in nontraditional forms different from the usual wires, cables, and tapes. In the future this possibility may be of special importance for utilizing high-temperature superconductors. Shortcomings of the superconducting helicoids are also mentioned. They are thermomagnetic instability and electrical losses, both resulting in charging rate limitations. The design and test results of model helicoids are presented: a NbTi coil with ID=180 mm OD=320 mm: a NbTi racetrack with large and short axes of 120 mm and 48 mm, respectively; and a Nb/sub 3/Sn coil with ID=46 mm, OD=120 mm. The racetrack winding without any bandages reached its critical parameters almost without training. The charging rate of the Nb/sub 3/Sn helicoid was much higher than that of NbTi coils. The total induction of the Nb/sub 3/Sn coil tested in a bias field was about 10.5 T. |

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.
