| Abstract | A compact high temperature superconductor magnet cooled by a single stage Gifford-McMahon cryorefrigerator was designed, manufactured and tested. The arrangement of the magnet was optimized to maximize cooling efficiency of the Bi2223/Ag winding and minimize the heat generation by eddy current losses during high-speed excitation. To achieve wide angular access and adequate magnetic field homogeneity in the magnet center a split-pair coil configuration was used. Maximum magnetic field in the magnet center is 1.8 T @ 14.5 K, inner diameter of the magnet winding is 50 mm, outer diameter is 98 mm and total width of the magnet winding including 14.2 mm air-gap is 72 mm. Performance of the magnet was tested also at liquid nitrogen, sub-cooled liquid nitrogen and liquid helium temperatures. New vacuum cryostat system with a free access to the magnet space was designed and manufactured. Calculations of the magnet behavior with iron poles were evaluated and compared with the magnet without iron. Experimental results agree well with the magnet parameters obtained by FEM simulation |

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.
