| Abstract | A new type of optical imaging X-ray detector with a capillary plate was constructed. The instrument consists of a CGPC (Capillary Gas Proportional Counter), a focusing mirror system, and an image intensified CCD camera. Both the charge signal and the light signal from the CGPC were proportional to energy up to hard X-rays of 60 keV. The light output of the CGPC was approximately 250 times larger than that of a NaI(Tl) scintillator. The light yield of the CGPC at gas gain of 300 was 1.2 photons per electron for a gas mixture of xenon +5% methane at 1 atm. Using the optical imaging detector, an image of a track due to an /spl alpha/-particle was detected. Also the first evidence was obtained that the light emission was due to gas multiplication occurring in a thin capillary. Our goal is to use this new type of optical imaging detector as an X-ray polarimeter. |

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.
