| Abstract | The multiple-beam accelerator MBE-4 is a device for research toward a heavy ion driver for inertial confinement fusion based on the induction linac concept. Its main goal is proof of the principle of current amplification by acceleration and controlled self-similar beam pulse compression. Into the 16-m long electrostatic alternate-gradient focusing lattice four beams are injected. Each carries an initial current of 10 mA of Cs/sup +/ ions from a Marx-driven diode at 200 keV. The current amplification is up to ninefold, with a final beam energy in excess of 800 keV in the middle of the current pulse. Available diagnostics include transverse double-slit emittance and position measuring devices; current-sensing Faraday cups; and electrostatic energy analysis. Diagnostic access is possible along the entire device at a number of stations and is fully computer controlled. The longitudinal and transverse properties of the 10-mA beams with and without acceleration are being studied. The diagnosis of the transport of a 100- mu A pencil beam, 1.5 mm in diameter, through an accelerating channel of a 5.7-cm diameter has begun. This beam has been used to determine the zero-current phase advance for various beam and machine parameters and to address some mechanical alignment issues as well. |

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.
