An extremely rare event in the world of particles has taken place during a Chinese-led study at the Large Hadron Collider (LHC) near Geneva, Switzerland.
And the event has scored yet another victory for the Standard Model – our current best theory to describe how the basic building blocks of the universe interact.
Sifting through experimental data collected between 2016 and 2018, researchers from Peking University and their colleagues from around the world spotted the simultaneous appearance of three force-carrying particles, known as bosons, which had never been seen together before. READ MORE...
High-energy laser weapons can now operate ‘infinitely’, thanks to a new cooling system that completely eliminates the build-up of waste heat
The technology could significantly change the face of battle by extending engagement times, and increasing range and damage, researchers say
Chinese military scientists have announced a major breakthrough in laser weapon technology, claiming they have developed a new cooling system that allows high-energy lasers to operate “infinitely” without any build-up of waste heat.
According to scientists at the National University of Defence Technology, in Changsha, Hunan province, the new cooling system completely eliminates the harmful heat that is generated during the operation of high-energy lasers. The issue has been a major technical challenge for laser weapon development.
With the new technology, weapons can now generate laser beams for as long as they want, without any interruption or degradation in performance.
“This is a huge breakthrough in improving the performance of high-energy laser systems,” said the team led by laser weapon scientist Yuan Shengfu in a paper published on August 4 in Acta Optica Sinica, a Chinese-language peer-reviewed journal.
“High-quality beams can be produced not only in the first second, but also maintained indefinitely,” they said.
The new cooling system uses advanced structures and optimised gas flow to remove heat from inside the laser weapon, while minimising turbulence and vibration and improving mirror cleanliness.
It has the potential to significantly change the face of battle by extending engagement times, increasing range and damage, and reducing logistics and costs, according to the researchers. READ MORE...
China launched construction of the world’s most powerful pulsed magnet facility in the city of Wuhan on Tuesday.
The upgraded pulsed high magnetic field facility at Huazhong University of Science and Technology will produce a short – but extremely strong – magnetic field at 110 Tesla, more than two million times stronger than that of the Earth.
The current record of 100 Tesla for pulsed magnetic field is held by a facility at the Los Alamos National Laboratory in the US state of New Mexico.
The strongest pulsed magnetic field that China can generate at present is 70 Tesla. READ MORE...
