| Abstract | Summary form only given, as follows. A dual plasma layer is created in magnetized radio frequency inductively coupled plasma. The effects of the external magnetic field and anode voltage on the evolution of the cylindrical luminous dual plasma layer from the anode glow are investigated in magnetized hydrogen plasmas. The anode glow is initially produced from the additional DC discharge which forms when a cylindrical anode platform inserted into the plasma diffusion region is positively biased. If the anode voltage is sufficiently high, the anode glow is transformed into an elongated luminous dual layer around the anode in the plasma diffusion region, in which a diverging magnetic field is coupled with an external magnetic field. The weakly magnetized plasma is needed for the formation of this double layer, and there is an upper limit on the magnetic field strength, beyond which the dual plasma layer disappears. The dependence of the dual layer structure on the magnetic field strength, anode voltage and the neutral gas pressure are also studied. The double layer structures are visually apparent because of the enhanced light emission from the neutrals excited by the energetic electrons. Some photographs of these structures will also be shown to demonstrate the phenomenon. |

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.
