| Abstract | Within the DETNI project prototypes of three novel position sensitive thermal neutron detectors types and adequate readout electronics have been developed. The detectors are based on thin solid neutron converters together with two-dimensional readout structures for the detection of secondary particles induced by the neutron capture. They aim at global count rates of up to 100 MHz together with a high spatial and time resolution. In order to utilize these detector characteristics new frontend and data acquisition electronics was required. A novel channel-wise self-triggered ASIC has been developed, which is able to cope with such high count rates and which complies with the signal specifications of the three different detector types. It provides time and analog information of a neutron event with a time resolution of 2 ns. For the data acquisition electronics, which will be described in this paper, prototypes of a clock distribution system and of a FPGA based readout system have been developed with current state-of-the-art electronics. The clock distribution system is to provide high precision, high frequency clock signals to the frontend, which is required to achieve the desired time resolution. The FPGA based readout system is to read out time stamp and analog information of the ASICs, carry out the digitization and transmit the data stream to a host PC |

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.
