| Abstract | This paper presents the design and experimental test results of a CMOS monolithic pixel sensor prototype with an optimized layout of the pixel cell aimed at a superior radiation tolerance. The chip implements transistors designed both with and without Enclosed Layout Transistor (ELT) rules, and different optimizations of the charge collecting diodes. Irradiations up to a total dose of 1.1 MRad and single particle detection tests have been performed with 200 keV electrons in view of the utilization of such a sensor in Transmission Electron Microscopy (TEM) applications. The sensor response to high-momentum particles was tested on a 1.5 GeV electron beam. The chip radiation tolerance was also assessed against a 2 MRad total dose of 29 MeV protons and against 1–14 MeV neutron fluences in excess of $10^{13}$ n $cm^{−2}.$ These tests show an improved performance of pixels with ELT transistors, a thinner oxide on top of the diode surface and guard-rings around the diodes. |

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.
