| Abstract | Summary form only given. So far our detailed analysis of a plasma-filled diode was largely based on the work of Brendan Godfrey published in a seminal paper of 1987. Having extended Godfrey's analysis from /spl alpha/=1 to /spl alpha//spl ne/1, where /spl alpha/=n/sub i0//n/sub e0/ is the ion/electron number densities ratio at the entrance electrode, we have been able to show that the diode can operate in four distinct regimes: stable, oscillatory, chaotic and unstable (Chen and Lindsay, 1996). The oscillatory regime, which is of importance in such microwave devices as vircators, was so far limited to a hydrodynamic model (Chen and Lindsay, 1997). However we know that in the case of a vircator in particular, oscillations may occur by reversal in the direction of the electron flow, a new regime of operation which lies outside the hydrodynamic model. This regime can be handled only either by using a large number of electron sheets in place of an electron beam of by employing a powerful PIC code, in our case MAGIC2D/3D. In our contribution we propose to present the analysis of our enlarged system together with the results of some early computations, in particular the range of system parameters for which virtual-cathode type of oscillations are likely to occur. |

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.
