| Abstract | The “Heavy Flavor Tracker” (HFT) is an approved micro-vertex detector upgrade to the STAR experiment at RHIC, consisting of three subsystems with various technologies of silicon sensors arranged in 4 concentric cylinders, to be installed in STAR by 2014. This new vertex detector will improve the track-pointing resolution in STAR to a DCA of ∼30 µm in order to allow for a direct and full topological reconstruction of heavy quark meson decays and a better determination of the heavy quark meson spectra. The two innermost layers of the HFT close to the beam pipe, the Pixel (“PXL”) subsystem, employ CMOS monolithic active pixel sensor (MAPS) technology that integrates the sensor, front-end electronics, and zero-suppression circuitry in one silicon wafer. The PXL layers of the HFT will consist of 400 MAPS sensors arranged in 40 ladders (10 ladders at a radius of 2.5cm and 30 ladders at 8cm from the beam), each containing 10 of these sensors. This paper will present selected design characteristics of the PXL detector part of the HFT and the hardware and firmware architecture of the proposed readout system for this detector, as well as its integration into the existing STAR framework. A prototype of this readout system has recently been used at CERN to take data from a telescope consisting of 7 sensors arranged in parallel planes and shown to be fully functional. |

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.
