| Abstract | The studies on the high temperature superconducting(HTS) current lead for superconducting magnets are actively underway with rapid advancement in HTS conductor technology recently. HTS current lead play a role to connect the external power supply with superconducting magnet and to block conduction heat invasion from room temperature. HTS current lead consists of several HTS tapes in parallel which are soldered to the copper blocks. Based on current technology, because critical current of HTS tape along the length is different, it is difficult to make HTS current lead composed of HTS tapes with the same critical current. Therefore, the magnetic quench in HTS tape with lowest critical current among HTS tapes in charging of transport current are generated firstly. Conventionally, HTS current lead uses voltage taps to detect magnetic quench but it is difficult to estimate quench of HTS current lead in fault because quench voltage level of a HTS tape is too low. Therefore, in this study, magnetic quench detection of HTS current lead using hall probe was investigated. The magnetic field distributions in octagonal shape of HTS current lead before and after magnetic quench in charging of transport current were computed using FEM. And a octonal shape of HTS current lead was fabricated and tested in order to measure the central magnetic field of HTS current lead. Based on the results, the application feasibility of the magnetic quench detection of HTS current lead using hall probe was investigated. |

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.
