China plans world’s most powerful particle collider

Beijing: Chinese scientists have completed an initial conceptual design of a super giant particle collider which will be bigger and more powerful than any particle accelerator on Earth, the media reported on Thursday.

“We have completed the initial conceptual design and organised international peer review recently, and the final conceptual design will be completed by the end of 2016,” Wang Yifang, director of the Institute of High Energy Physics, Chinese Academy of Sciences, told the China Daily.

The institute has been operating major high-energy physics projects in China, such as the Beijing Electron Positron Collider and the Daya Bay Reactor Neutrino experiment.

Now scientists are proposing a more ambitious new accelerator with seven times the energy level of the Large Hadron Collider in Europe.

With a circumference of 50 to 100 km, the proposed Chinese accelerator Circular Electron Positron Collider (CEPC) will generate millions of Higgs boson particles, allowing a more precise understanding.

“The technical route we chose is different from LHC. While LHC smashes together protons, it generates Higgs particles together with many other particles,” Wang said.

The Higgs boson factory is only the first step of the ambitious plan. A second-phase project named SPPC (Super Proton-Proton Collider) is also included in the design — a fully upgraded version of LHC.

LHC shut down for upgrading in early 2013 and restarted in June with an almost doubled energy level of 13 TeV, a measurement of electron volts.

Google Claims It Has “No Plans” To Relaunch A Search Engine in China

Technology companies have recently been a favorite target of many members of the U.S. Congress, who have criticized them over a wide range of issues such as privacy, work in China and allowing foreign meddling in U.S. elections.

The United States’ top general said on Thursday that the Chinese military was benefiting from the work Alphabet Inc’s Google was doing in China, where the technology giant has long sought to have a bigger presence.

“The work that Google is doing in China is indirectly benefiting the Chinese military,” Marine General Joseph Dunford, chairman of the Joint Chiefs of Staff, said during a Senate Armed Services Committee hearing.

“We watch with great concern when industry partners work in China knowing that there is that indirect benefit,” he said.

“Frankly, ‘indirect’ may be not a full characterization of the way it really is, it is more of a direct benefit to the Chinese military.”

Last year Google said it was no longer vying for a $10 billion cloud computing contract with the U.S. Defense Department, in part because the company’s new ethical guidelines do not align with the project.

In June, Google said it would not renew a contract to help the U.S. military analyze aerial drone imagery when it expires, as the company sought to defuse an internal uproar over the deal.

At the same time, Google said it has “no plans” to relaunch a search engine in China, though it is continuing to study the idea.

During the hearing, Republican Senator Josh Hawley sharply criticized the tech company, referring to it as “a supposedly American company.”

Asked about Dunford’s comments, Google referred to previous statements.

Google Chief Executive Sundar Pichai has previously said the company has invested in China for years and plans to continue to do so, but that the company also was continuing to work with the U.S. government on projects in health care, cybersecurity and other fields. (VOA)
