| Abstract | To be position sensitive, silicon drift detectors (SDDs) require a trigger signal synchronous with the interaction time (i.e., the start of the electrons' motion) since the interaction position along the drift coordinate is obtained from the measurement of the electrons' drift time. In the case of a photon interaction, the trigger must be provided by the detector itself. One way to obtain a fast trigger signal exploits the induction signal given by the holes collected by the p/sup +/ strips close to the interaction point. We have designed and instrumented a multilinear SDD especially intended to study the self-triggering technique and its application to two-dimensional (2-D) X-ray position sensing. The measured position resolution along the drift coordinate is of the order of 10 ns with 10 keV photons, leading to a position resolution of 30 /spl mu/m rms at typical drift velocities. A comparable position resolution can be obtained on the lateral coordinate. By engineering the electron trajectory in the collection region, the anode capacitance can be minimized (<0.1 pF) leading to excellent energy resolution even at room temperature. |

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.
