Elite Ushio lights the way to next-gen computer chips in Japan
Chipmakers have spent two decades pouring investment into a revolutionary new technique to push the limits of physics and cram more transistors onto slices of silicon. Now that technology is on the cusp of going mainstream, thanks to a secretive Japanese company that’s mastered the skill of manipulating light for applications from squid fishing to cinema projection.
3rd Kamiokande to be built
The science ministry is planning to build a next-generation elementary particle detector, the Hyper-Kamiokande, in Hida, Gifu Prefecture, sources said.
Shaken and stirred: Scientists capture the deformation effect of shock waves on a material
Understanding how shock waves affect structures is crucial for advancements in material science research, including safety protocols and novel surface modifications. Using X-ray diffraction probes, scientists at the Institute of Materials Structure Science of KEK (High Energy Accelerator Research Organization), Tokyo Institute of Technology, Kumamoto University, and University of Tsukuba studied the deformation of polycrystalline aluminum foil when subjected to a laser-driven shock wave.
IPNS KOTO Experiment at J-PARC Hadron Experimental Facility Broke World’s Best Sensitivity on Rare Neutral Kaon Decay by an Order of Magnitude - first step forward elucidation of “matter-antimatter asymmetry”
An international collaboration reported the first major results from the experiment KOTO, which is being conducted at the Hadron Experimental Facility of Japan Proton Accelerator Research Complex (J-PARC). The KOTO collaboration set the upper limit of once in three hundred million on the rate of the neutral K-meson (kaon)#1 decay#2,3 into a neutral pi meson and a pair of neutrinos from the analysis of the data set collected in 2015, and improved the world’s best sensitivity by an order of magnitude. The collaboration has begun to elucidate the matter-antimatter asymmetry (CP symmetry breaking) in the universe through kaon decays. As the prospects for future, further improvements on the sensitivity with data collected since 2016 are anticipated. The collaboration upgraded the KOTO detector in the autumn of 2018, and started to take the new data with it in February 2019.
