| Abstract | Summary form only given. Thyratrons are still widely used in high power pulse applications. A system able to measure cathode state and thereby predict remaining tube life would be a very valuable system tool. This paper discusses how such a system could be implemented. Thyratron triggering circuits have to survive a very large grid to cathode voltage spike each time the thyratron switches on. This spike becomes larger and longer as the tube ages, but also, more importantly, if the thyratron pre-fires (switches on without trigger pulses). Grid spikes are often the reason for damage to the trigger generator circuit. The characteristics of the grid spike, however, ought to give a useful prediction of the overall behavior and ageing characteristics of the tube. If implemented such a system could permit planned maintenance and minimize down time of a system. The paper will describe a technique that provides both trigger circuit protection and a monitor of spike behavior that can be used to gam an indication of overall remaining tube life. The paper will also give an overview of the characteristics of thyratron triggering and how they influence the spike. The protection and monitoring systems that will permit useful tube characteristics to be displayed will be described along with practical results and implementations. |

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.
