Times Cited Count：96 Percentile：92.88(Physics, Fluids & Plasmas)The positive or negative ion sources which form the primary components of neutral beam injection systems used in magnetic fusion have to meet simultaneously several demanding requirements. This paper describes the underlying physics of modern positive ion sources, which provide the required high proton fraction (
90%) and high current density (
2 kA/m
) at a low source pressure (0.4 Pa) with a high electrical efficiency and uniformity across the accelerator grids. The development of negative ion sources, which are required if high energy neutral beams are to be produced, is explained. The paper reports that negative ion sources have achieved many of the parameters required of sources for the neutral beam injectors of future fusion devices and reactors, 200 A/m of D
at low pressure, 
0.3 Pa, with low co-extracted electron content. The development needed to meet all the requiremens of future systems is briefly discussed.

A new framework of information provision and public dialogue concerning safety of nuclear facilities has been proposed in this paper. Basic ideas behind the framework are a novel concept of safety named Safety-II and a relevant emerging methodology of safety management called Resilience Engineering. The new ideas emphasize practices that contributed to positive outcomes in addition to failures and errors experienced during accident management. Implication of the new framework concerning the nuclear risk communication has been addressed through reflection of several field experiences.
