| Abstract | The closing switch is the main device to control the power supply of an ElectroMagnetic Launcher (EML) system. Three types of closing switch which included a triggered vacuum switch (TVS) and two air spark gaps (ASGs) named ASG-1, ASG-2 and ASG-3 with different configuration in trigger unit were described for investigating the delay characteristics, high current capacity and erosion characteristics. A LC resonant circuit was set up and connected with the TVS's and ASG's main electrodes. A design circuit for controlling the TVS and ASGs was proposed. The trigger energy of the controller can be adjusted conveniently. By means of changing the trigger energy, the experimental data show that the delay time and jitter time decrease with increasing the trigger energy. The delay time and jitter time decreases magnificently with increasing the voltage in main gap. The improvement in the structure and controller of the TVS and ASG is a good way of decreasing the delay time and jitter time. It shows that TVS-2 has better performance in delay time and jitter time than TVS-1. Generally, ARG-2 and ARG-3 have shorter delay time than TVS-1 and TVS-2, as the initial plasma would be generated much more easily and quickly in the air than that in the vacuum case. ASG has a shorter delay time and lower needed minimum breakdown voltage than TVS. The results show that TVS is a better choice than ARG with insignificant erosion. |

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.
