Recently, basing on optical-feedback cavity-enhanced absorption spectroscopy (OF-CEAS) technology, a research team led by Prof. ZHANG Weijun from Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS) successfully detected OH radicals at 2.8 μm wave length with a distrib...
With good properties, heavy/high-Z metal material has been considered as the first choice for plasma facing components in International Thermonuclear Experimental Reactor (ITER). However, at thermonuclear fusion relevant temperatures, the accumulation of heavy/high-Z particles (impurities) in the...
Neutron, as an electrically neutral particle, has a strong penetrability and always emits secondary gamma rays during the particle collision process. The scientific and efficient scheme of shielding neutron is to select high Z (atomic number), low Z materials, and neutron absorbing materials simu...
The certified power conversion efficiency (PCE) of Organic-inorganic hybrid perovskite solar cells can exceed 25.5% currently. However, stability remains the dominating obstacle in practical applications as it’s easy to degrade when exposed in air. Scientists have been trying to make the device ...
For every fusion facility around the world, it is striving for steady state fusion reaction with operation period as long as possible. However, it is not easy. Many challenges stand in the way. Reliable divertor scenario with high power handling capability is key among that.
