Abstract | Ultra-low-jitter repetitive solid state picosecond switching is being developed for application to electromagnetic impulse sources. Ultra-low-jitter and fast risetime are required to synchronize multiple modules of radiating array sources. Laser controlled photoconducting switches provide low jitter but have limited lifetime and are too expensive for many commercial applications. The authors are studying an alternative method using inexpensive delayed avalanche breakdown semiconductor closing switches in an artificial transmission line configuration to generate powerful electromagnetic shockwaves. As an example of the new technology, the authors present experimental results for a miniature (volume <25 cm/sup 3/) 3 kV pulser which provides RMS jitter of 16 ps with 100 ps risetime at 2 kHz repetition rate. The miniature pulser employs 18 delayed breakdown silicon avalanche switches in a differential shockline topology. SPICE-based circuit modeling results are compared to experimental measurements. The circuit modeling includes effects of stray capacity and a Monte-Carlo jitter analysis. The picosecond pulsers can be used for impulse sources, Pockels cell drivers, trigger generators and pulse power applications. The modeling techniques are applicable to Marx generators and circuits containing large numbers of switches with capacitive cross coupling. |

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.
