| Abstract | The injection kicker systems for the two LHC beams will each consist of four magnets and four pulse forming networks (PFNs), discharged by thyratron switches. Fast resonant charging systems (RCS) are used to charge the PFNs within 1 ms to 60 kV: fast charging minimises the number of unwanted erratically thyratron discharges. The stability and pulse to pulse reproducibility of the PFN voltage must be maintained to a precision of /spl les//spl plusmn/0.1%. Each RCS consists of a 2.4 mF primary capacitor bank, connected via a Gate Turn-Off thyristor (GTO) and a 1:23 step-up transformer to two PFNs, each with an effective capacitance of 0.96 /spl mu/F. The PFNs are discharged 400 /spl mu/s after the end of the charging period into the kicker magnets. The RCS include novel features such as a GTO used in Gate Assisted Turn-off (GAT) mode and a low-leakage inductance, high voltage, step-up pulse transformer. This paper presents a basic design for the RCS, and the optimisation of the electrical circuit using PSpice. The RCS are designed, constructed and tested at TRIUMF in collaboration with CERN as part of the Canadian contribution to the LHC project. |

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.
