| Abstract | The paper considers energy losses in the plasma of the plasma opening switch (POS) used for a power intensifying in high power pulsed generators. Energy losses due to intensive ion flows during the conduction phase are responsible for the current "switching" in conductive plasma. Experimental results of both active resistance performance and energy losses are reported. Being combined with the data on current layer MHD penetration and corresponding increase in inductance this allows to measure the POS resistance components due to both plasma acceleration and resistance. Energy loss evaluation based on this measurement is reported. It demonstrates that POS dissipates up to 20% of the energy stored in the inductance. Electrical parameters for the experiment were as follows: 0.4 /spl mu/F pulsed voltage generator capacity, 200 kV output generator voltage, 120 kA drive current amplitude and 1 /spl mu/s quarter of the current period. |

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.
