| Abstract | Summary form only given. Previous work on the ubitron oscillator included the derivation of a linear theory for the cavity's start of oscillation current, the development of a nonlinear simulation code, and the design of a compact 1 GW 21% effcient source for directed energy applications. Recent design efforts have increased the interaction efficiency to 46% using axial mode profiling in a TE/sub 011/ diffraction coupled cavity. In this technique, which is widely employed in gyrotrons, the radius of the cavity is tapered so that the peak of the wave's field is displaced towards the output end. The beam then bunches more adiabatically in a lower rf field level while transferring its energy quickly in a higher field level. Additionally, the usage of diffraction coupling alleviates axial mode competition due to the decrease of cavity Q with axial mode number. A design for a 46% efficient S-band oscillator along with a 3.6 kA annular electron gun will be presented. |

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.
