| Abstract | Summary form only given. To achieve high efficient harmonic gyro-amplifier, gyro-peniotron research is underway at NRL using axis-encircling beam and magnetron-type slotted waveguide structure. The device performance depends critically on the quality of the electron beam. After several years' efforts, a new type axis-encircling gun with triple pole piece and center post, has been designed and fabricated by Litton. Electron ray trajectory calculations for the gun, performed using the deformable mesh code DEMEOS at Litton, indicate that the beam of /spl Delta/v/sub z//v/sub z/<3% and /spl Delta/rg/rg<6% can be realizable at beam velocity ratio(/spl alpha/) of 2 using 70 kV, 3.5 A beam. The microperveance of the beam was measured to be 0.216 up to 70 kV. Experimental work is in progress to characterize the electron beam a and electron beam alignment using capacitive probes, and axial velocity spread using a movable collector. Initial test shows the measurement agrees reasonably well with the simulation. The detailed experimental results will be presented and compared with simulation. |

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.
