Wigo, I think that attributing every thing to culture factor is illogical and self-deceiving. Isn't culture created by people? Chinese never discouraged the exploration of nature although they could put higher priority in some other areas.

I think there are many Chinese working at Silicon Valley, right? Anyway, today you need large techonolgy and economical resources to become a great mathematician, physicist, whatever. China will get this soon.

On the other hand, the West didn't give any Nobel Prize in Economics to any Chinese despite of the China's economic miracle, which is being the greatest in world history. So, China may have to develop its own resources before their geniuses can be recognised at maths, economics or whatever. The West only recognises the West (and its ass kissers, of course)

I agree. Let's leave the races part. It will only arouse flame despite our intention.

China set to make fusion history

Plasma physics comes under scrutiny in new breed of tokamak.

Ichiko Fuyuno

The world's first fully superconducting tokamak is soon to produce a discharge of ionized gas or plasma.

If all goes as planned, China's Experimental Advanced Superconducting Tokamak (EAST) project will make its first plasma in the next few weeks.

EAST uses superconducting coils to create a magnetic field that confines plasma inside a doughnut-shaped vessel known as a tokamak. The behaviour of the plasma should shed light on the potential of nuclear fusion as an energy source.

Conventional experimental fusion machines use copper coils, or a combination of copper and superconducting coils, to trap the hot plasma. But copper coils heat up and need to be cooled down regularly, thus limiting operating time. EAST has only superconducting coils so it can be operated continuously.

The US$25-million machine sets the stage for the multibillion-dollar ITER fusion experiment that is to be built in France; ITER, due to start operations in 2016, is similarly designed to be all-superconducting.


"We'll need new energy resources for a long-term period, and fusion will be one of them," says Peide Weng, deputy manager and chief engineer of the EAST project at the Institute of Plasma Physics of the Chinese Academy of Sciences. "For commercial use, it should be superconducting because it will need continuous operation."

China approved the machine in 1998, as part of a push towards new energy sources. Construction then began in 2000 in Hefei, in southern China. The 150-member EAST team imported some material and components, but designed and fabricated the bulk of the equipment on its own.

EAST is only one-tenth the volume of Japan's JT-60 tokamak, and one-hundredth the expected volume of ITER. It won't produce fusion power, and is designed to study advanced tokamak physics. The first plasma, created from heated hydrogen gas, will probably last for only a few seconds. Still, "it will be a very important step forward," says Toshihide Tsunematsu, director-general of the Naka Fusion Institute of the Japan Atomic Energy Agency, who visited EAST a few weeks ago. The agency owns the JT-60 tokamak.

Eventually, the EAST team aims to hold a plasma for study for as long as 1,000 seconds. In other tokamaks plasmas last for only a few tens of seconds.

South Korea is currently developing a tokamak similar to EAST, called the Korean Superconducting Tokamak Reactor (KSTAR), whose construction is expected to be completed at the end of 2007. Japan also plans to upgrade its JT-60 machine to make it fully superconducting in a few years.

International physicists praise what China has accomplished so far. In 2003, 25 physicists visited EAST as part of its international advisory committee.

"Everybody came away very impressed," says Dale Meade, a physicist with the Princeton Plasma Physics Laboratory in Princeton, New Jersey, and a member of the group. The committee plans to hold another meeting in October, when China hosts a conference of the International Atomic Energy Agency.

In the meantime, the EAST researchers have plenty to work on, says Tsunematsu. They will have to improve key technologies, such as a device to heat the plasma, and be able to effectively control high-temperature plasma for a long period of time. "China will face a real challenge," he says.

连自然杂志都报导了，怎么国内还没有消息？

[kelvinyang]

I have been waiting for the news for two weeks. The experiment was originally set for the date of August 15th, but no news have come out so far. There could be something wrong so that the schedule was delayed.
I am a physicist and I learned the working principle of Tokamak fusion reactor while I was in college. I really want to see something breakthrough in this field. The world needs new source of energy.

I think its something to do with the education system, which from what I heard only emphasises high pressure rote learning; which stifles creativity and initiative. Perhaps this is related to the cultural explanation given by wigo.

Almost all Chinese historians and Western sinologists give culture explanation for why modern sciences were not founded and modern technologies were not invented in China. However, they completely ignore an undeniable fact that Chinese people created Chinese culture. The culture explanation is implicitly a cyclic logic and a paradox. The logic problem of the culture explanation will be more apparent if I rephrase it this way: Chinese invented a culture that made them less inventive.

I would rather speculate that Chinese lack a particular unknown gene or God enjoys playing a die to determine which group of people going to lead the earth than accept the culture explanation.

Hey, maybe I am a genius. I can see something that other scholars do not see.

No matter what, this education system we've got gave us a pretty high average. End of story.

中国首个核聚变实验装置成功放电


中国致力推动核聚变研究（新华社图）

中国的核聚变实验装置成功放电，引起了人们对热核能源新的关注。

新华社报道说，中国科学家周四（9月28日）在设在安徽合肥的全超导热核装置上成功进行了放电实验。

由中国自行设计、研制的世界上第一个全超导非圆截面核聚变实验装置(托卡马克，EAST，原名HT-7U)位于中科院等离子体物理研究所，今年2月到3月完成调试。

等离子体研究所的程艳女士说，这次放电实验被视为成功，因为反应装置实现了等离子体放电。

她说，“这代表人类对核反应的研究又迈出了一步。”

报道指出，这个核聚变装置在真空和低温条件就位后，研究人员就等离子体纵场磁体和12个极向场磁体分别进行了260次通电测试。

在试验过程中，最长通电时间达到5000秒，最大电流达到8200安培，相对应的装置中心场强已达到2特斯拉，和有关系统以及等离子体控制系统等运行正常，保证了通电测试的安全和成功。

“人造太阳”

中国媒体以“人造太阳”来形容这项试验。它以探索无限而清洁的核聚变能源为目标。

热核聚变反应和太阳产生的原理相同，而且相对现在的核能分裂发电厂，产生较少的放射性核废料。

领导这项试验的科学家说，试验结果将有助于正在法国建造的一个规模大得多的国际核聚变项目。

不过观察人士警告说，即使有关项目按照计划进行，仍需数十年的时间才可以建立一个商业性的核聚变反应堆。

同时，科学家将要克服的挑战包括如何生产多于控制核聚变所消耗的电力。

中国和美国等国家致力推动核聚变研究，希望得到较清洁而且潜力无限的能源。

为了国家荣誉和减少对进口原油及污染严重的煤炭依赖，北京政府极力推动核聚变研究。

EAST的两个基本参数是：等离子体释放时间为5000秒，放电时间是3秒。
不简单啊！
我要喝酒庆祝！

[kelvinyang]

That is not a great data. The key parameter should be the energy gain, which is not mentioned. I suspect that the energy gain is still negative.

[wigo]

EAST是托卡马克，不是反应堆。

[kelvinyang]

I know. I spent one year in learning plasma physics including tokamak. The current world record of discharge time is about 30 seconds (from Japan). The first EAST experiment only has 3 seconds. Of course, EAST has potential to break the record.
