| Abstract | The CTF3 (CLIC Test Facility 3) will produce 1.56/spl mu/s long intense electron pulses. The unbundled 5.4A beam of the injector will have a transverse beam size/spl sim/1mm. After the buncher the current is reduced to 3.5A and the transverse size varies between a few hundred micrometers and one millimetre along the length of the linac. Calculations indicate that these beam parameters will impose an unbearable thermal load for the intercepting screens currently in use (scintillators and aluminium OTR foils). Graphite and SiC have been investigated as possible alternative materials for the OTR radiators. The possibility of replacing scintillating screens with OTR targets at the low energies of the injector has also been considered. A possible limitation in the use of such high temperature radiators has been identified; ions released from the heated target could focus further the beam with the risk of damaging the target itself and/or blowing up the beam. This would also affect the emittance measurement and would hinder any effort to detect head-tail phenomena. This paper gives the results of the theoretical estimations, and of the beam-based experiments. |

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.
