| Abstract | The new 1.4 MeV/u prestripper linac at GSI will provide intense ion beams to fill the synchrotron SIS to the space charge limit for all elements up to uranium. The design mass to charge ratio A/q is 65, the effective acceleration voltage of the 30 m long linac is up to 91 MV. The design beam current in emA is 0.25/spl middot/A/q, i.e. 15 mA of U/sup 4+/. This linac will replace the 27 MHz Unilac Wideroe section which was designed for A/q-values below 24. All cavities of the new linac are operated in the H/sub 110/-mode. The 9.2 m long IH-RFQ with an energy profile from 2.2 keV/u to 120 keV/u has been completed and RF tuned. RF power tests were performed successfully on 2 out of 10 tank modules. The drift tube linac consists of two 42 MV IH cavities. The 'Combined Zero Degree Structure' KONUS allows to accelerate the beam by a total number of 99 gaps with only 5 quadrupole triplet lenses for transverse focusing. The experience from the construction and from the RF tuning of all cavities is reported as well as the measured quality and shunt impedance values. The running in of the new prestripper linac is scheduled from April to September 1999. |

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.
