|Abstract||An international tritium model validation experiment was held at Chalk River, Canada, during June 1987. The Princeton Plasma Physics Laboratory (PPPL) Differential Atmospheric Tritium Sampler (DATS) was one of the many types of tritium samplers used for this experiment. Besides the modeling data that were produced from this experiment, the authors learned how well our tritium samplers performed when a known tritium quantity was released. The DATS were set up at 50, 100, 200, and 400 meters downwind from the release point. Data were collected during the release period and for the next 24 hours. While the units worked very well in the field, valued operational experience was gained in the recovery of the tritium from the silica gel. Because of delays in the analysis of the collected samples, it became difficult to recover the HTO fraction quantitatively. Indications are that molecular sieves are more suitable for samples which are not going to be processed immediately. This paper reports on the field set up, the measurement results, and operational experience.|

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.
