| Abstract | Generation of molybdenum plasma by a long pulse is reported. Optimization of various experimental parameters (pulse delay, pulse energy ratio, target positioning, etc.) together with appropriate excitation scheme and pumping geometry allows to achieve the initial stages of lasing regime even for pulse energies below 1 Joule. The intensity of the X-ray laser radiation depended on the delay between the long and short pumped pulses. Maximal signal was registered at 0.5 - 1-ns delay. A ratio between the heating pulses' energies (k = E/sub fs// E/sub ps/) has changed from 0.3 to 10. The optimal conditions in this geometry were found to be at k = 3. Another important parameter is the distance between the target and focal point of femtosecond radiation. The maximal signal was registered at the distance of 0.2 - 0.3 mm from the Mo surface. The full energy of the pumping radiation was less than 0.5 J. |

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.
