| Abstract | Summary form only given, as follows. Summary form only given. In order to enhance the power capability of the helix traveling wave tube, a novel helical slow wave structure (SWS) supported by 8 wedge shaped discontinuous dielectric pillars which exist only at the helix tape in each pitch, is developed in this paper. Each pillar can be easily brazed with the helix tape and the metal envelope by means of a special soldering way. This kind of discontinuous support mode can safeguard the dielectric supporting pillar not be broken due to the thermal stress in the case of high temperature. A hybrid model is developed, which can be used to analyze the dispersion characteristics and interaction impedance of the tape helix, by considering the helix radial thickness and the influences of these discontinuous dielectric pillars. The dispersion equation and interaction impedance of this kind of helical SWS are obtained. The numerical calculating results using this hybrid model presented in the paper show good agreements with the HFSS simulation results. All the results presented here can provide a strong basis on design of this kind of novel helical slow wave structure. |

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.
