| Abstract | Summary form only given. A self-magnetically insulated transmission line (MITL) has been designed to transmit a 1 MA 100 kV pulse with a 70 ns rise-time from a Linear Transformer Driver (LTD) to a wire array z-pinch load. The transmission line has three stages: a coaxial line, followed by a radial line, and finally a conical line to the load. The transmission line geometry was chosen to ease construction and to lower cost while maintaining a low inductance. Both collisionlessand collisional MITL models were used to determine the lower limit of the anode-cathode gap for the transmission line. A third case assuming vacuum insulation with a limiting electric field of 200 kV/cm in the transmission line was also investigated. The transmission line inductance in each of these cases was calculated analytically, and a PSpice simulation of the circuit was used to compare the performance of the designs. Assuming the z-pinch load inductance was approximately 3 nil, the collisional and collisionless MITL models each met the goal of a 1 MA pulse with a 70 ns rise-time. The vacuum insulation design did not meet these requirements. The anode-cathode gap in the collisional MITL design was expanded until the transmission line inductance reached 4 nH, such that the current pulse shape still met the preset goals and a factor of safety was added to reduce the possibility of arcing. This MITL design will be constructed and implemented on the LTD z-pinch being constructed in 2007 at the University of Michigan. |

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.
