| Abstract | A new concept of polyimide electrical insulation for superconducting cables of accelerator magnets was developed in the last years. Its enhanced He II permeability allows a significant improvement of the heat extraction from the coil. This cable insulation concept is used for the quadrupole magnet prototype for the insertion region of the High Luminosity-Large Hadron Collider project. It aims at pushing the limits of the Nb-Ti technology to withstand high heat deposition. Cable samples wrapped with the new insulation scheme were characterized from the thermal standpoint, as well as from the electrical and mechanical ones. In particular, heat transfer measurements from insulated cables towards the helium cooling bath were performed in a coil-like configuration. Various wrapping schemes were tested in different mechanical conditions, and a model was developed to explain the experimental results. The paper summarizes the main results of all these investigations. |

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.
