| Abstract | The BESIII thin superconducting solenoid will generate 1.0 T central field with a field uniformity of 5% within the drift chamber. The superconducting coil winding has an ID of 2962 mm, an OD of 3002 mm and a length of 3550 mm. The overall magnet cryostat has an I.D. of 2750 mm (warm bore), an O.D. of 3390 mm and a length of 3910 mm. Rectangular Aluminum Stabilized Nb-Ti/Cu Superconductor, 3.7 mm /spl times/ 20 mm, is employed to wind the one-layer coil inside a hoop-force support cylinder. The winding is indirectly cooled by forced-flow two-phase liquid helium. The thermal shield is also indirectly cooled by two-phase liquid nitrogen circulating in a tracing tube. The 4.5 K coil together with its support cylinder weighs 3583 kg. It is supported by twenty-four radial supports and twenty-four axial supports. The supports are designed for electromagnetic de-centering forces of 63.7 kN radial and 122.3 kN axial in addition to a 3 g axial and radial acceleration load. The 80 K thermal shields are supported by eight cold mass supports against 3 g load. The detailed magnet and cryostat design and the design of cold mass support and the coil fabrication process will be discussed. |

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.
