| Abstract | The migma concept is being pursued at Fusion Energy Corporation as a means of achieving controlled fusion.1-4 The features which distinguish this concept from other controlled fusion concepts may be summarized as: 1. High energy 2. Ordered motion 3. Use of advanced fuels 4. Small physical size Beams of ions are injected into the field of a superconducting magnet at MeV energies. The resulting motions of trapped ions have a high degree of order in phase space compared with a thermalized gas. At MeV energies the two major ion loss mechanisms, charge transfer and multiple Coulomb scattering, are greatly suppressed compared with thermonuclear energies (1-100 keV), because the cross section for multiple Coulomb scattering falls off as T1-5 and that for charge transfer approximately as T-5. Because ions are injected at nearly the average energy of the migma, it may also be said that, as a practical matter, the use of ordered motions facilitates the attainment of colliding energies in the MeV range. The ion motion is essentially that of precessing orbits which all intersect within a central core that is small compared with a gyrodiameter. Motion along the magnetic field lines is confined by a non-adiabatic focusing. The high collision energies obtainable enable the use of what are called "Advanced Fuels," that is, fuels other than the deuteriumtritium (D-T) mixture planned for, e.g., the tokamak fusion reactor. These fuels require higher collision energies for useful reaction rates. |

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.
