| Abstract | Summary form only given. The pseudospark discharge is a low pressure (10-100 Pa of hydrogen or helium) gas discharge in a coaxial electrode geometry. Both, cathode and anode are built as hollow electrodes and have a central bore. For the use as a fast closing switch at least 10/sup 9/ electrons have to be injected into the hollow cathode to ignite the discharge with low timing jitter. Within some tens of nanoseconds the discharge runs through different modes and the switch impedance drops to very low values. A typical pseudospark switch (3 mm electrode distance, 3 mm electrode holes, 4 mm electrode thickness) was run in a circuit with low current rise (10/sup 9/ A/s) to prolong the discharge phases. Different investigations (spectrally resolved fast shutter photography and photo multiplier measurements, determination of the electron beam passing into the hollow anode by a Faraday cup, measurement of the forward voltage drop FVD by two high voltage probes) were performed. Results of these measurements are compared to quantitative measurements of the metal vapour density by laser induced fluorescence. Possible mechanisms of the different discharge phases are discussed. |

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.
