| Abstract | Four monitors are installed in LEP (Large Electron-Positron colliding beam accelerator), two per particle type. Two of the monitors are at dispersion-free locations which permit measurement of the transverse emittance, estimation of the energy spread and detection of various instabilities. The light has its origin in the main bending magnets. The source is imaged onto the detectors by means of catadioptric optics. Two detectors are used, one a charge coupled device (CCD) matrix and the other made up of a fast optoelectronic shutter and wavelength shifter coupled to a CCD matrix. Observations can either be made in the normal TV mode or in digital modes where one or more profiles (burst mode) are stored on the CCD and then digitized. In the burst mode, up to 18 profiles separated by 1 to 256 turns can be acquired. The results are presented either as data mixed with the TV picture or as two or three dimensional plots and projections on a workstation. Results and present performance are presented. |

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.
