| Abstract | Summary form only given, as follows. The operation of the PASOTRON (Plasma-assisted slow-wave oscillators) is studied in the BWO regime. The absence of the guiding magnetic field in this device allows for the 3D motion of beam electrons. Recent studies showed the possibility of obtaining high efficiency up to 50 %. This was realized due to not only 3D motion but also due to properly optimized reflections from the slow wave structure ends in the experiment. The effect of the boundary reflection on the PASOTRON BWO is investigated theoretically. A stationary solution for the backward wave field amplitude is obtained in a self-consistent treatment of the wave excitation in the helix BWO with beam electrons 3D motion inside. The device electron efficiency and the oscillation frequency were obtained given a certain boundary reflection coefficient. At each value of the reflection coefficient, a number of different modes can be excited depending on the beam current. The efficiency of each of these modes was calculated. The results of this study can be used to increase the device efficiency, through adjusting the boundary reflection coefficient to the proper value. |

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.
