| Abstract | A fast-wave ICRF (ion cyclotron range of frequencies) antenna being designed for Alcator C-MOD is described. The antenna is in many respects prototypical of the baseline launcher design for the Compact Ignition Tokamak (CIT). The C-MOD launcher has a single current strap, with a strap and cavity geometry very similar to one quadrant of the CIT launcher (which has four straps in a 2*2 configuration). The antenna fits entirely within an 8-in-wide by 25-in-long port and is radially movable over a distance of 15 cm. It will operate at a frequency of 80 MHz for pulse lengths up to 1 s, at a maximum power level of 2 MW, corresponding to a power flux of >1.5 kW/cm/sup 2/. The antenna is an end-fed, double-loop configuration in which the current strap is grounded in the middle to provide mechanical support. The design includes a disruption-support system that accommodates thermal expansion of the antenna box while supporting large disruption loads. It also includes a matching system consisting of an external resonant loop with two shunt capacitors serving as tuning/matching elements.< |

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.
