| Abstract | Summary form only given. Results of parallel-plate plasma opening switch (POS) experiments on HAWK are presented. The Hawk generator produces a sinusoidal output current of amplitude /spl sim/750 kA and quarter period /spl sim/1.2 its. The POS used is a tri-plate with a single cathode and two anode plates, each 15 cm wide. The plasma is injected from plasma guns through slots in the anodes. This POS performs almost as well as a comparable coaxial POS for short-circuit load shots with conduction times less than 700 ns. The parallel plate geometry provides much better diagnostic access than the standard coaxial POS. Framing camera images of the plasma imply that the current snowplows until it reaches the end of the injected plasma and opens near the cathode. A two-color laser interferometer is used to measure the electron and neutral densities of the plasma in the switch and in the magnetically insulated transmission line (MITL) between the switch and load integrated along chords in the /spl theta/-like direction. The electron density measured in the injected plasma region rises sharply during conduction and falls rapidly near the time of opening consistent with a snowplow traveling through the injection region. |

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.
