Times Cited Count：749 Percentile：99.93(Physics, Fluids & Plasmas)The Progress in the ITER Physics Basis document is an update of the ITER Physics Basis (IPB), which was published in 1999. The IPB provided methodologies for projecting the performance of burning plasmas, developed largely through coordinated experimental, modeling and theoretical activities carried out on today's tokamaks (ITER Physics R&D). In the IPB, projections for ITER (1998 Design) were also presented. The IPB also pointed out some outstanding issues. These issues have been addressed by the International Tokamak Physics Activities (ITPA), which were initiated by the European Union, Japan, Russia and the U.S.A.. The new methodologies of projection and control developed through the ITPA are applied to ITER, which was redesigned under revised technical objectives, but will nonetheless meet the programmatic objective of providing an integrated demonstration of the scientific and technological feasibility of fusion energy.

The development of diagnostics for ITER is a major challenge because of the harsh environment, strict engineering requirements and the need for high reliability in the measurements. A number of R&D tasks have been identified by the International Tokamak Physics Activity (ITPA) as "high priority" and form the focus of current work: (1) Review the requirements for measurements of the neutron/alpha particle source profile and assess possible methods of measurement, (2) Development of methods to measure the energy and density distribution of confined and escaping a-particles, (3) Determine any additional tests and measurements needed of the irradiation effects on candidate materials and sensors used for diagnostic construction, (4) Determine the life-time of plasma facing mirrors used in optical systems, (5) Develop the requirements for measurements of dust, and assess candidate techniques for the measurement of dust and erosion, (6) Assess the effects of radiation on magnetic coils used for measurements of the plasma equilibrium and support the development of new methods to measure steady state magnetic fields accurately in a nuclear environment. This paper will report on recent achievements in these tasks.

This paper summarises recent progress in the physics basis and its impact on the expected performance of ITER. Significant progress has been made in many outstanding issues and in the development of hybrid and steady state operation scenarios, leading to increased confidence of achieving ITER's goals. Experiments show that tailoring the current profile can improve confinement over the standard H-mode and allow an increase in beta up to the no-wall limit at safety factors 
4. Extrapolation to ITER suggests that at the reduced plasma current of 12MA, high Q 
10 and long pulse (1000 s) operation is possible with benign ELMs. Analysis of disruption scenarios has been performed based on guidelines on current quench rates and halo currents, derived from the experimental database. With conservative assumptions, estimated electromagnetic forces on the in-vessel components are below the design target values, confirming the robustness of the ITER design against disruption forces.
