Abstract | The X-ray emission from a low energy (2.3 kJ) Mather-type plasma focus operated with hydrogen filling is investigated. Specifically the X-ray emission in 5.0-9.0 keV and 13.0-25.0 keV energy range is studied by inserting a tungsten metallic disc at the copper tapered anode tip. Filtered pin diodes are used as time resolved X-ray detectors whereas a pinhole camera is employed for time integrated analysis. The X-ray flux from the focus region is observed measurable within the pressure range 0.25-3.5 mbar of hydrogen filling. The maximum emission in 4/spl pi/-geometry is estimated as 3.43 /spl plusmn/ 0.05 J and corresponding wall plug efficiency for X-ray generation is 0.15 %. The X-ray emission is found dominantly as a result of electron beam activity on the anode tip that is confirmed by the images recorded by the pinhole camera. |

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.
