| Abstract | The superradiative regime of relativistic BWO allows achieving not only extremely high microwave power but under some conditions also the very stable parameters (peak power, central frequency and RF phase relatively voltage rise time) from one pulse to another. The moderately dispersive spread of group velocities in the frequency band of short microwave pulse might plays the important role for the peak power hold. The results of experiments on pulse-periodic generation of X-band (9.7 GHz) short pulses are presented. Microwave pulses with peak power up to 2 GW and 0.7 ns duration were produced with the use of magnetic field in the slow wave structure as high as 2.2 T. The repetition rate was 100 p.p.s. for the batches with duration up to 2 sec. The cathode voltage was of 370 kV and beam current was 4 kA. Conditions of stable output power value were found when the root mean square deviation of detector signals was in two times less than rms of accelerating voltage pulses. Because of the rise time of cathode voltage should be optimal, the ferrite-loaded section of coaxial transmission line was used. This method of voltage pulse sharpening could provide the reduction of rise time from 2.5 to 0.6 ns at the level 300-400 kV. |

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.
