| Abstract | In the effort to further understanding of the Jovian moon Europa, a Jet Propulsion Laboratory (JPL) and Applied Physics Laboratory (APL) joint team are developing the Europa Clipper spacecraft concept that would provide multiple flybys of Europa during its tour. During the flyby maneuvers, the proposed Europa Clipper spacecraft would be required to operate within the high radiation environment. In order to protect the sensitive electronics of the spacecraft, the current radiation protection approach is to locate these electronics within a radiation vault. This paper documents the study performed addressing the construction and geometry of this electronics radiation vault. The method of development incorporated analytical base panels of various thicknesses comprised of standard aerospace materials (aluminum and titanium). These panels were then subjected to a range of seed loads in order to create a preliminary rib pattern. Panels where the baseline thickness is not adequate to provide the necessary shielding will then have additional shielding applied in the form of Tantalum sheet added to either the internal or external faces in order to account for the capability differences. Further vetting of the panel geometries will then take into account factors such as manufacturability, flexibility to late shielding requirement changes, assembly mass, and additional design requirements finally selecting a baseline configuration to be implemented in the flight design. Detailed analysis will be performed for an idealized panel which will not be required to support any additional components; however aspects such as harness pass-through, thermal impacts, and accessibility will be addressed. |

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.
