| Abstract | This paper discusses a theoretical and experimental investigation of parameters of plasma [hydrogen (H2) and argon (Ar)] developed in an inductively coupling plasma reactor. The reactor was shaped as a planar chamber inserted between two gaps formed between two separated identical halves of a quasi-closed solenoid cut along its diameter and powered with a 13.56-MHz RF to generate a closed loop of alternating magnetic field crossing the reactor chamber twice. It has been shown that the solution of the Hamilton-Jacobi equation describing motion of a charged particle with the certain momentum in a radial cylindrical wave generated in a gap of the quasi-closed solenoid can be presented as the particle motion along a closed Fig. 8-type trajectory. Simple estimation based on this solution has shown that energy of plasma electrons captured and accelerated in the gap at reasonable power applied to the solenoid should run up to ~ 70 eV. Experiments have shown that in the reactor filled with H2 at 6 mtorr and powered, for example, with 2 kW of 13.56-MHz RF, the electrons accelerated in electromagnetic fields were arranged in three distinct populations: 1) electrons of ~ 130-eV energy detected as stable electron flows; 2) certain portion of electrons mentioned in 1) diffused on neutrals and forming in velocity space a layer with thickness ~ 6 eV at average energy ~ 100 eV; and 3) a small population of cold electrons of ~ 20-eV energy in plasma potential vicinity. It has been shown also that the certain disposition of one of the quasi-closed solenoid halves with respect to the other one leads to the electron energy variation at approximate conservation of their density for all of the electron populations in the range from ~ 6 to ~ 100 eV. The same effect can be obtained by shift of phase of the RF source powering one of the solenoid halves with respect to the other one. |

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.
