| Abstract | For the toroidal ATLAS magnet system, some 90 km of aluminum stabilized conductor are required. The conductor is a Rutherford cable, coextruded with very pure aluminum. The main characteristics of the conductor are: (1) a very large critical current, 60 kA at 5 T and 4.2 K; (2) RRR of the stabilizing aluminum of at least 1000 on the finished conductor; (3) a good bonding between the Rutherford cable and the stabilizer: a shear stress of 20 MPa is required; and (4) 1750 m of unit length. To assure a good quality of the conductor all along the production and to minimize the risk of rejection of such expensive units, a strict quality assurance was established. The paper describes the results of the R&D phase to set all parameters to produce the first two unit lengths necessary for the winding of the B0 coil (a 9 m long model coil of the ATLAS Barrel Toroid). It also describes the control system based on continuous ultrasonic inspection, able to provide images of the cable inside the aluminum that is used to evaluate on line the quality of aluminum to cable bonding. |

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.
