| Abstract | In this paper, we propose a concept for a novel high voltage low impedance surface discharge switch. The mechanism of surface discharges in gas was investigated on the nanosecond scale by Mesyats (2005). The important parameters which determine the switching performance of a pulsed-charged surface discharge switch, namely breakdown voltage, breakdown jitter and multi-channelling behaviour are controlled by dimensions of the discharge gap, the characteristics of the dielectric, the type and pressure of the gas and the rise time of the applied voltage pulse. The number of channels formed in a surface discharge switch is mainly a function of the applied voltage pulse (dV/dt > 1 $kV/ns^{)2}.$ The breakdown mechanism of a surface discharge switch was investigated by Reinovsky and Goforth (2004). A novel design of high voltage low impedance surface discharge switch was simulated in CST Microwave Studio. The basic design parameters were 2 nanosecond pulse length, very low characteristics impedance (2 Omega) and 1 nanosecond rise time. A high dielectric constant causes a low impedance, while keeping the distance between the powered electrode and the grounded base plate large enough to prevent breakdown. The switch has been constructed and the first results of the experiments 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.
