Significant advances have been made in the confinement of reactor-grade plasmas, so that we are now preparing for experiments at the power breakeven level in the JET and TFTR experiments. In ITER we will extend the performance of tokamaks into the burning plasma regime, develop the technology of fusion reactors, and produce over a gigawatt of fusion power. Besides taking these crucial steps toward the technical feasibility of fusion, we must also take steps to ensure its economic acceptability. The broad requirements for economically attractive tokamak reactors based on physics advancements have been set forth in a number of studies. An advanced physics data base is emerging from a physics program of concept improvement using existing tokamaks around the world. This concept improvements program is emerging as the primary focus of the U.S. domestic tokamak program, and a key element of that program is the proposed Tokamak Physics Experiment (TPX). With TPX we can develop the scientific data base for compact, continuously-operating fusion reactors, using advanced steady-state control techniques to improve plasma performance. We can develop operating techniques needed to ensure the success of ITER and provide first-time experience with several key fusion reactor technologies. This paper explains the relationships of TPX to the current U.S. fusion physics program, to the ITER program, and to the development of an attractive tokamak demonstration plant for this next stage in the fusion program.Abbreviations used TFTR

Muon physics and the application of muon technique is an interdisciplinary research which involves particle physics, material science, condensed matter physics, biomolecular science, and archaeology. Many important researches have been done and published in these areas by scientists from North America, Europe, and Japan. Due to the lack of accelerator-based muon source in China, Chinese research groups in these fields mainly rely on overseas muon facilities or on joining international collaborations. Some recent major progress on muon physics and muon technique application, and the prospects of the design, construction, and application of the accelerator-based muon source in China were reported in this paper. 相似文献

There is a renewed interest in nuclear power worldwide. The interest is sparked by concerns about global warming and security of energy supplies. In addition to the growing interest in building more reactors in countries that already have nuclear power, future demands for nuclear power are likely to include applications in countries that do not presently use nuclear power and applications beyond large-scale electricity generation. This paper will discuss some of the characteristics that future reactors will need to have to meet such demands, as well as other measures required to facilitate a nuclear renaissance. In addition, the emergence of new international nuclear initiatives and their potential roles will be described. 相似文献
