| Abstract | A design using two 250-mA beams on two lithium targets has been proposed to maximize the test volume while minimizing the flux gradients. A spatial, energy-, and angle-dependent neutron source model the D-Li reaction was used to provide a 3-D map of uncollided flux within the test volume. An optimization of the uncollided flux showed that approximately 8 l of test volume with uncollided fluxes of 10/sup 14/ n/cm/sup 2//s is available with flux gradients <10%/cm. The collided flux within the test volume was then determined by coupling the source model with a Monte Carlo computation. The spectral effect of the high-energy tail was evaluated as to possible impact on materials response. Calculations comparing the radiation damage to materials from the D-Li source to that caused by a standard DT-fusion first-wall neutron flux spectrum show that the He and dpa production, as well as the ratio He/dpa and dpa/MW/m/sup 2/ are within 30% for the two sources.< |

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.
