According to the research plan of the EAST physics experiment, two sets of neutral beam injectors （4-8 MW, 10-100s） were built and operated in 2014. We present the development of the EAST neutral beam injector （NBI） and the latest experiment results obtained on the test-stand about operation of ion source, beam extraction, and measurement of key parameters. Those results show that all targets reach or almost reach the design targets. All these lay a solid foundation for the achievement of plasma heating and current drive for EAST in 2014.展开更多

The theme of this year＇s GRC on DBPs was ＂Disinfection 2100： Linking Engineering, Chemistry, Toxicology, and Epidemiology to Reduce Exposure to Toxicity Drivers while Curtailing Pathogens＂ （GRC, 2017）. More than one hundred and fifty scientists from around the world actively participated in the week-long conference.展开更多
