| Abstract | Summary form only given. As part of a collaborative effort into investigating pulsed power driven high brightness X-ray sources Sandia National Laboratories has conducted a series of experimental runs with the Self Magnetic Pinched (SMP) diode on the RITS-6 accelerator. The annular electron beam of the SPM X-ray source is capable of pinching tightly to pencil size spot size with a large forward directed radiation dose. Coupling of power flow as well as interactions of the electron beam with plasmas from ionized gases of the anode can greatly influence the radiation dose and spot size. Cathode diameter, geometry, and AK gap are key factors in optimizing the operation of the SMP diode. Time integrated spot sizes under 3 mm and forward directed dose in excess of 200 rads at 1 meter were observed. Voltage calculations from radiographers equations are also given which are consistent with PIC simulations. PSF derived from the Barnea square aperture method. Measurements of the time varying behavior of the spot size as well as movement from center will also be presented. |

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.
