| Abstract | Summary form only given, as follows. We have already shown that the application of the higher harmonic modulation principle to the winding law of the helical coil of the L=1 and L=2 Heliotron/Torsatron can reduce magnetic force on the helical coils. This finding is important from the viewpoint of the coil supporting technology of superconducting magnets. Also it was shown that proper values of the higher harmonic modulation constants can effectively produce the magnetic well in a vacuum field. The presence of the magnetic well generally means the possibility of high beta operation, where the beta is plasma pressure/magnetic pressure. We will present calculations for magnetohydrodynamic (MHD) equilibrium of plasmas with non-zero beta values and for the dependence of the beta-limit on the variation of the modulation constants. The latter is important from the economical standpoint of plasma confinement properties of the helical device. For these calculations a three-dimensional MHD spectral inverse equilibrium code VMEC was used. |

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.
