| Abstract | A one meter long plasma source has been developed for studies at the Stanford Linear Accelerator Center (SLAC) for plasma wakefield excitation by a 30 GeV electron beam in an extended plasma column. The plasma is formed by ionization of a Li-vapor with an ArF excimer laser (193 nm). The Li-vapor is produced in a heat pipe oven which will be installed in the electron beam transport line. Through control of the oven temperature, neutral vapor densities reaching 2/spl times/10/sup 15/ cm/sup -3/ are produced. We report the details of the oven construction and temperature profile measurements with and without Li vapor. In the experiment, the excimer laser will be located about 15 m away from the plasma source. Beams produced by excimer lasers operating with a stable resonator cavity are unsuitable due to the large number of modes present in such beams. A significant reduction of the modal content has been obtained through the use of an unstable resonator design. Results of the implementation of this cavity configuration on the propagation characteristics of the excimer beam will be presented, including the design of the final telescope for spot size reduction. |

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.
