| Abstract | Summary form only given, as follows. Theory and experiments indicate that post acceleration can reduce ion divergence. In addition, overall system efficiency should be better in multistage accelerators. Yet even the small step from single-stage to the use of two acceleration stages introduces a significant increase in the system complexity. As an example, the ion beam must remain space-charge-neutral between acceleration stages and the use of a conventional gas cell results in beam stripping. Diode configurations to circumvent this problem are presented. Another issue is the effect of diamagnetic pressure on the virtual-cathode of the second stage, which causes a bending of the magnetic flux surface that defines the virtual cathode. This results in a focusing of the ions beam. Analytic calculations of this process are presented. Divergence reduction during post acceleration depends of the level of electromagnetic fluctuations generated by instabilities in both stages. Three dimensional particle-in-cell simulations are presented to study this process. |

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.
