| Abstract | Summary form only given. The performance of cyclotron autoresonance maser amplifiers can be significantly improved by using a properly spatially profiled helical wiggler. The enhancement process derives from the unique property of electron orbit in a combined solenoidal and wiggler field. A properly imposed wiggler gives rise to an electron orbit which acts to selectively inhibit autoresonance acceleration of electrons by the electromagnetic wave. The proposed configuration is able to alleviate the severe problem of performance degradation by beam velocity spread. Simulation results show that, by using a 500 kV and 200 A pencil beam, more than 20% output efficiency can still be attained at 94 GHz, even with 5% beam velocity spread. If higher output power is desired, both beam voltage and current could be increased. We will address the effects of beam AC space charge on the amplifier performance. |

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.
