| Abstract | Summary form only given. Microhollow electrode discharges (MHCD) are gas discharges between closely spaced (submillimeter) electrodes containing openings with diameter, D, on the same order as the electrode gap. Reducing the size of the cathode opening to 100 /spl mu/m has allowed us to generate stable, direct current discharges in argon and xenon up to atmospheric pressure, in air up to 400 Torr. Results of previous experiments with a hollow electrode configuration in air at several Torr indicated the presence of an "electron-beam" emitted through the anode hole. Experiments in a similar geometry but at much higher pressure, in air and in argon, point again to the fact that the energy distribution of the electrons emitted through the anode hole is anisotropic, with a strong component in forward direction. The dependence of the directed emission of electrons through the hollow anode from the hollow cathode discharge parameters, was studied in argon and air for pressures up to several hundred Torr, using a third, biased electrode as electric probe. A model for the observed directed electron emission, and its effect on the sustainment of a large volume discharge between hollow anode and the third electrode will be presented. |

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.
