| Abstract | A C-band (5,712 MHz) RF system for an e+e- linear collider at 500 GeV center-of-mass energy requires total 4,080 units of 50 MW pulse klystrons and matching 111 MW peak-power modulators for two main linacs. An initial design value of the wall plug power for the entire RF system is 150 MW with 2.5 /spl mu/sec RF pulse width and 100 Hz pulse repetition rate. A detailed circuit analysis shows that it is possible to get the overall RF system efficiency of approximately 24%, or equivalent to 210 MW wall plug power. This includes 85% DC high voltage charging efficiency using compact inverter power supplies, and 70% pulse efficiency using 3.5 /spl mu/sec pulse length (ESW) with less than 1% flat top ripple, and auxiliary powers for thyratron heater, klystron heater, focusing magnet, pulse transformer reset, and etc. |

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.
