| Abstract | This study deals with a new demonstration technique of full-field transmission soft X-ray imaging microscopy. The microscope's resolution is measured by utilizing a new type of test patterns, by the use of multilayer coatings. Processed with conventional TEM sample preparation technique, the cross sections of the coatings can be thinned to be sufficiently transparent for imaging in the microscope. Resolution measurements are done by using test patterns which consist of forty chromium/silicon bilayer pairs, with measured periods of 39.0 nm and 48.6 nm. At the half-periods of 19.5 nm and 24.3 nm, the modulations measured from the lineouts are 20% and 75%, respectively. A straight-line approximation between the measured points indicate that the microscope achieves the 26.5% modulation at a half-period of 20 nm. The calculated resolution, based on evaluation of the Hopkins theory of partially coherent imaging, is 19 nm. The microscope is thus 1.1/spl times/ diffraction limited at /spl lambda/ = 2.07 nm. |

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.
