| Abstract | Recently, major projects, for the transmutation of nuclear waste, the production of tritium or more generally for the production of neutrons by spallation, have been proposed using high power linacs and a CW operation. In this context, the manufacturing of the low or medium energy part of the linac with a standard DTL, appears to be a tricky job, particularly the insertion of high gradient quadrupoles into the drift tubes, with a specific cooling system needed for CW operation, and many brazing or welding processes. Moreover the reliability and the maintenance of the DTL could be affected sooner or later. It is proposed in this paper to use a DTL with short tanks (let say 2 to 5 cells) with a focusing system outside the tanks. The mechanical design is in that way very simplified, the drift tube geometry can be optimised for a better shunt impedance, the cooling system is easy and efficient and the alignment problem is greatly reduced. This concept is applied to a 5 MeV to 100 MeV CW proton linac operating at 352 MHz, with a 40 mA beam current, and shows moreover that the linac global efficiency is increased compared with a classical approach. Preliminary beam dynamics studies are included. |

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.
