| Abstract | A discussion is presented of the microwave and beam optics parameters of a chopper-prebuncher injection system and a 55-MeV, 2998-MHz, 2.8-m-long accelerator waveguide assembly designed to produce inherently sharp beam energy spectra (0.5%) over a range of booster injection pulse periods from approximately 200 to 1.5 ns. The DC-biased 2998-MHz chopper and prebuncher system is designed to inject into the accelerator waveguide sharply defined bunches with essentially all of the charge contained in less than 15 degrees of longitudinal phase space and with a narrow spread of electron velocities. Also, the single-section, nonuniform impedance waveguide structure is designed to prevent energy spectrum broadening (typically from asymptotic off-crest bunch location during acceleration) by combining correlated energy-phase orbits with a nodal detuned circuit arranged to give two opposing over-the-crest phase drifts when the linac is operated at precisely six times the booster frequency. |

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.
