| Abstract | Results of experimental studies of anode foil destruction mechanisms are presented. The experiments have been done on the accelerator with the following parameters: voltage - up to 500 kV, e-beam current - up to 10 kA, pulse duration (FWHM) - 60 ns, pulse repetition rate - up to 3 Hz. It was found out that the formation of cathode spots on the anode foil surface as well as the current in the diode during the positive post-pulses following the main negative pulse of the accelerating voltage are the main reasons for the foil life time limitation. The improvement of the diode impedance matching with the output impedance of the pulsed power generator decreases the energy of the post-pulses and leads to a longer life time of the anode foil. The introduction of an additional anode electrode forming with the cathode a vacuum crowbar switch practically excludes damages of the anode foil and increases its life time up to $10^{5}$ pulses. |

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.
