| Abstract | We provide here an update on the status of ferratron development. The ferratron is a high-voltage, fast risetime, gas switch with low-jitter and high repetition rate. It is triggered by the emission of electrons from a ferroelectric device. It may be suitable for phased arrays due to it's low jitter. We have designed and built a test chamber for measuring the output of the ferratron. The test chamber is designed to launch a fast-risetime wave into an electrically large coaxial structure. The transition from gas to oil is accomplished with a polyethylene lens with one surface being a hyperbola of revolution. The goal of the transition is to preserve the risetime of the wave as it transitions from gas to an electrically large oil coax. We provide here preliminary data on the test chamber characteristics, in terms of both TDR (time domain reflectometry) and TDT (time domain transmission). We have included in our test chamber a method of connecting the gap to a feed cable, in order to drive the gap with a known source for calibration. We demonstrate that the risetime of the test chamber in time domain transmission (TDT) mode is around 50 ps, which is sufficiently fast to measure the anticipated 100 ps risetime of the pulses to be generated by the ferratron. We also provide measurements of the switch in a hybrid trigatron ferratron mode. |

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.
