Abstract | Summary form only given. Breakdown in an AC Plasma Display Panel (PDP) cell depends upon the electrode geometry and voltages, the initial wall charge, secondary emission coefficient, and the gas pressure and composition. Secondary electrons, ejected by ion impact on a dielectric-coated cathode, accelerate in the strong fields of the cathode fall, generating an avalanche of ionization events. The ions generated accelerate toward the cathode, sustaining the secondary current. When the electric field gradient is large over an electron scattering mean free path, electrons are not tied to the field lines, resulting in a spatial distribution of ionization-generated ions returning to the cathode. In this work, we consider a simple 3 electrode structure with a neon-xenon gas mixture. Using a Monte Carlo technique with the XOOPIC code, the ion distribution functions are mapped along the secondary emitting dielectric surface for the initial fields. An amplification factor can be defined along the secondary emitting surface which can be coupled with the spatial distribution of the ion flux. This technique provides a description of the initiation of the breakdown, including the locations where the discharge is amplified. The technique is readily extended to include mapping the amplification factor for discharges in progress, by including immobile space charge and surface charge. |

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.
