| Abstract | Summary form only given. In recent years more interest is being shown in nanosecond discharges in high-pressure gases, formed in non-uniform electric field. Previously, a cathode with small- curvature radius was used, and the gap was applied with high voltage pulses with amplitude up to 400 kV. In these conditions the runaway electrons and (or) X-ray radiation are registered, and the discharge plasma may be used as a source of spontaneous and laser radiation, and as a source of X-ray radiation with high pulse repetition rate up to 3 kHz. However, the volt-ampere characteristics of nanosecond discharges were less studied mainly due to difficult recording the discharge current pulses with subnanosecond resolution. This work was to investigate the character of discharge current flowing in a gas diode, used for supershort avalanche e-beam generation (SAEB), and to determine the time of SAEB generation with respect to the discharge current pulse. A discharge of atmospheric pressure air in a non-uniform electric field has been investigated. Formation time of a supershort avalanche electron beam with respect to the discharge current pulse was defined. It has been shown that SAEB is recorded in a volume discharge at the current pulse front, and the SAEB maximum current is achieved before the first peak of current at the discharge current front, that is determined by the gas diode capacitance discharging through plasma. At that, with the use of RADAN-220 generator, and an insulator made of a standard vacuum X-ray tube IMA- 350D, SAEB appearance advances the first peak by ~100 ps. The recorded amplitudes of the bias currents were above 1 kA. The mentioned bias currents appeared due to charging of the capacitor, which was formed by the dense plasma with its front expanding from the cathode and the fiat metallic anode. |

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.
