| Abstract | Summary form only given, as follows. Soft X-ray emission from a short vacuum gap, operated with repetitive low-current arc with peak current of 200 A and period of /spl sim/ 2 /spl mu/s was investigated. The repetitive discharge was generated by simply limiting the current from capacitor bank by a resistor. Point-like soft X-ray source was generated by using low bank voltage (/spl sim/ 20 kV) and short gap length (200 pm) to achieve small source size and high current density while preventing severe electrode damage. The electrode materials were copper, stainless steel of grade SUS304, silver and tungsten. Time-resolved soft X-ray intensity was monitored by a 2-channel filtered detector system composed of combination foil filters and fast, soft X-ray-sensitive scintillators and photo multipliers. The X-ray signals show that the most of X-ray radiation was emitted in period between arc extinction and subsequent breakdown, and that the X-ray intensity increased as the voltage between electrodes increased until the subsequent breakdown. The X-ray during this period was ascribed mainly to bombardment of anode by thermionic electrons that were emitted from high temperature region in the cathode surface, which is heated during arc phase. |

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.
