| Abstract | Results of theoretical and experimental research of excited in a Ar+Hg mixture microwave discharge as a source of optical radiation are presented. Much attention is given to a low pressures when "resonance" version of discharge, properties of which are prescribed by nonlinear processes developed near the plasma resonance (region where Langmuir plasma frequency is equal to the cyclic frequency of microwave radiation), is realized. Under the "resonance" conditions decreasing of pressure leads to the strong increasing of intensity of Hg radiation (including the biologically active UV) and to the fast diminishing of Ar lines radiation. Collisional-radiative model (CPM) of microwave discharge plasma based on a detail analysis of kinetics of population of excited states of Hg and Ar atoms has been developed. When behavior of calculated characteristics has been compared with the measured once qualitative verification of resonance effect of microwave energy absorption by discharge plasma has been received. Calculation performed in a framework of kinetic model describing population and depopulation of electron-excited states of Hg and Ar demonstrate a good correlation with the experimental results. Experimental and theoretical data have been used as the basis of discussing in this work construction of powerful microwave UV lamp. |

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.
