| Abstract | The LEP (Large Electron Positron colliding beam accelerator) Phase I high-power RF system, by which a total of 16 MW is generated at a frequency of 352 MHz, includes 16 1-MW CW klystron/Y-junction circulator assemblies and a WR 2300 waveguide system. Via the latter, the generated RF power is distributed and supplied to the 128 accelerating structures. All klystrons, circulators, and waveguide components have been delivered, accepted by CERN, and installed in the LEP tunnel. A general description of the RF generation and distribution system is given. The performance of the klystrons and circulators as well as results of the first high-power tests in the LEP ring tunnel are presented. In particular, the tendency of the klystrons to produce spurious sidebands at high output power levels is discussed and the means used to cure it to a large extent are described. Furthermore, an explanation is given of how the problem of frequency arcs in the waveguides between klystron and circulator was overcome. |

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.
