| Abstract | Summary form only given, as follows. The correlation between the onset times of X-ray emissions in three energy ranges has been studied on a plasma focus device (11 kJ at 16 kV) with various gas fillings. Soft X-ray line emission at about 1 keV photon energy (H- and He-like neon ion resonance lines) was detected by means of a crystal spectrometer. Medium energy X-ray emission (5-30 keV) was measured by filtered PIN diodes. Hard X-rays (energy above 100 keV) were detected by scintillator-photomultiplier detectors. In most of the measurements all detection devices were placed in a plane perpendicular to the electrode axis viewing a region at about 1 cm in front of the central electrode. The visible light emission from the collapsing plasma sheath was taken as the time reference in the correlation studies. It was found that the onset times of the plasma focus X-ray emission in the energy ranges specified above were highly correlated (correlation coefficients close to unity were found). This was not the case for the duration and intensity of the same emissions. |

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.
