| Abstract | The use of calorimeters with very small energy sampling fractions (of the order of a few percent or less) can result in small energy fluctuations in the showers which are interpreted as large equivalent energy depositions in the calorimeter. The authors studied the nature of such fluctuations in the forward hadron calorimeter system of the collider detector at Fermilab (CDF). The results are consistent with the hypothesis that the fluctuations are due to interactions of low-energy neutrons produced in the hadronic showers of the absorbed particles with the hydrogeneous material which makes up the calorimeter's structure or filling. These neutrons elastically scatter the protons in these hydrogen compounds, which heavily ionize the active media of the calorimeter, creating additional observed energy. The authors present the characteristics of the energy fluctuations and calculate an effective cross section for their production using data available from neutron source measurements and text beam and colliding beam runs.< |

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.
