Published New pumpkin shaped nucleus radiates protons with record setting rate
(via sciencedaily.com) A new atomic nucleus 149-Lutetium, consisting of 71 protons and 78 neutrons, has been synthesized.
Published Nuclear reactor power levels can be monitored using seismic and acoustic data
(via sciencedaily.com) Seismic and acoustic data recorded 50 meters away from a research nuclear reactor could predict whether the reactor was in an on or off state with 98% accuracy, according to a new study.
Published Selecting the right structural materials for fusion reactors
(via sciencedaily.com) Do two promising structural materials corrode at very high temperatures when in contact with 'liquid metal fuel breeders' in fusion reactors? Researchers now have the answer. This high-temperature compatibility of reactor structural materials with the liquid breeder -- a lining around the reactor core that absorbs and traps the high energy neutrons produced in the plasma inside the reactor -- is key to the success of a fusion reactor design.
Published Self-sustained divertor oscillation mechanism identified in fusion plasma experiment
(via sciencedaily.com) To harness the forces that power the Sun, researchers heat fuel to such a high temperature that atoms melt into electrons and nuclei to form a hot, gaseous soup called plasma. The plasma can rip through any material on Earth, so it must be confined by magnetic fields -- but it can only be controlled for short periods. Now, in a first step to prolonged control, researchers have discovered that the underlying mechanism mirrors the unlikely biological predator-prey model.
Published Deep neural network to find hidden turbulent motion on the sun
(via sciencedaily.com) Scientists developed a neural network deep learning technique to extract hidden turbulent motion information from observations of the Sun. Tests on three different sets of simulation data showed that it is possible to infer the horizontal motion from data for the temperature and vertical motion. This technique will benefit solar astronomy and other fields such as plasma physics, fusion science, and fluid dynamics.
Published Ushering in safe, low-carbon electricity generated by nuclear fusion
(via sciencedaily.com) Engineers are working to develop a new, economically viable and safe source of low carbon electricity through nuclear fusion.
Published Chaining atoms together yields quantum storage
(via sciencedaily.com) Original source Data stored in spin states of ytterbium atoms can be transferred to surrounding atoms in a crystal matrix.
Published Graphene and an intense laser open the door to the extreme
(via sciencedaily.com) Original source A research team has developed a large-area suspended graphene and irradiated the thinnest graphene target with an ultra-intense laser to realize high-energy ion acceleration. Their findings will be applied to the development of compact, efficient ion accelerators used for cancer treatment, nuclear fusion and so on.
