| Abstract | Summary form only given. Development work is underway on a high current (16 kA), mildly relativistic (400 kV), L-band Klystron source. The electron beam diode and rf extraction circuits are two key areas in this work. The diode is to provide approximately 7 GW of electron beam power for 1 microsecond for partial conversion to rf energy by a 2 or 3 cavity Klystron amplifier system. The present configuration will be shown. Results of calculations for the magnetic beam optics, electrostatic potential structure, and self-consistent emission PIC simulations will be presented. Experimental results will be shown of the vacuum diode performance. The intense beam emitted by the diode presents unique design complications in connection with extraction of rf power. Various considerations are discussed such as the trade-offs between beam potential and kinetic energies, optimum shunt, impedance values, and advantages of discrete vs. distributed circuits. The various circuits that have been considered include conventional single gap designs, a distributed interaction structure, and a single gap triaxial circuit. Designs have been analyzed using analytical methods, rf codes, and particle in cell simulations. A description of the experimental hardware is given along with results of cold tests and power extraction results. |

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.
