MD的NIF第一次点火成功，从科学的角度上讲，祝贺美国科学家

NNSA and LLNL announce first successful integrated experiment at NIF

WASHINGTON, D.C. – The National Nuclear Security Administration (NNSA) and Lawrence Livermore National Laboratory (LLNL) today announced that the National Ignition Facility (NIF) recently completed its first integrated ignition experiment. In the test, the 192-beam laser system fired 1 megajoule of laser energy into its first cryogenically layered capsule, raising the drive energy by a factor of thirty over experiments previously conducted at the Omega laser at the University of Rochester. With the completion of this test, NIF is beginning its next phase of the campaign to culminate in fusion ignition tests.

“NIF is an example of what the NNSA labs do best,” said NNSA Deputy Administrator for Defense Programs Don Cook. “We are bringing together the best minds in science, engineering and technology to solve some of the nation’s greatest challenges.

With NIF, the nation has a critically important asset that supports our national security priorities, pushes the frontiers of science and discovery, and carries the potential for critical advances in energy security.”

NIF, the world’s largest and highest-energy laser system, is expected to be the first laser system to demonstrate reliable fusion ignition – the same force that powers the sun and the stars – in a laboratory environment. When NIF’s lasers fire, more than one million joules of ultraviolet energy are focused into a pencil-eraser-sized gold cylinder that contains a peppercorn-sized plastic capsule filled with the hydrogen fuel.

The experiment demonstrated the integration of the complex systems required for an ignition campaign. This target was filled with a mixture of tritium, hydrogen and deuterium tailored to enable the most comprehensive physics, a necessary step on the path to demonstrating fusion ignition. All systems operated successfully, and 26 target diagnostics participated in the shot.

“From both a system integration and from a physics point of view, this experiment was outstanding,” said Ed Moses, Director of the National Ignition Facility. “This is a great moment in the 50-year history of inertial confinement fusion. It represents significant progress in our ability to field complex experiments in support of our NNSA Stockpile Stewardship, Department of Defense, fundamental science and energy missions.”

NIF was built as a part of the NNSA’s program to ensure the safety, security and effectiveness of the nuclear weapons stockpile without underground testing. With NIF, scientists will be able to evaluate key scientific assumptions in current computer models, obtain previously unavailable data on how materials behave at temperatures and pressures like those in the center of a star, and help validate NNSA’s supercomputer simulations by comparing code predictions against laboratory observations. Other missions include advancements in fusion energy technology and enabling scientists to better understand the makeup of stars in the universe and planets both within and outside our solar system.

The experimental program to achieve fusion and energy gain, known as the National Ignition Campaign, is a partnership among LLNL, the Laboratory for Laser Energetics at University of Rochester, Los Alamos and Sandia National Laboratories, and General Atomics. Other contributors include the Massachusetts Institute of Technology, the Atomic Weapons Establishment (UK), Commissariat à l'énergie atomique (France) and many others.

Established by Congress in 2000, NNSA is a semi-autonomous agency within the U.S. Department of Energy responsible for enhancing national security through the military application of nuclear science in the nation’s national security enterprise. NNSA maintains and enhances the safety, security, reliability, and performance of the U.S. nuclear weapons stockpile without nuclear testing; reduces the global danger from weapons of mass destruction; provides the U.S. Navy with safe and effective nuclear propulsion; and responds to nuclear and radiological emergencies in the U.S. and abroad.

Founded in 1952, Lawrence Livermore National Laboratory is a national security laboratory that develops science and engineering technology and provides innovative solutions to our nation’s most important challenges. Lawrence Livermore National Laboratory is managed by Lawrence Livermore National Security, LLC for the U.S. Department of Energy’s National Nuclear Security Administration.

人造太阳啊，牛啊，未来的新能源

这个装置最主要的目的还是为氢弹建模收集数据用的，可控核聚变发电算是顺带的

中國的是托卡馬克，無法應用在武器上
NIF的激光技術和聚變技術都可以用在武器上

那位老兄，你看不懂英文的么？文章中美国人自己都说了这个装置的主要目的是验证核武用的。

NIF was built as a part of the NNSA’s program to ensure the safety, security and effectiveness of the nuclear weapons stockpile without underground testing.

NNSA maintains and enhances the safety, security, reliability, and performance of the U.S. nuclear weapons stockpile without nuclear testing

Lawrence Livermore本来就是美国的国防实验室，说橡树岭有些项目和核武无关还差不多。美国人利用《全面禁止核试验条约》的条约漏洞，搞亚临界核爆试验，至少十几次了，这种擦边球都打，用NIF就不用打擦边球了，全世界的核试验探测装置都无法察觉NIF里进行的试验。

和科盲讲话实在是很累。中国的情况不用你担心，中国在这方面并不差，只是中国比美国人讲信用的多，我们从来不搞什么亚临界核爆。你美国爸爸有了新的核武试验装置，你应该高兴嘛，我以为这文章贴出来最high的不是我这种科技爱好者，而是抱美国的爱美国人士呢。

这种实验好像大家都搞吧 利用计算机模拟核爆 只不过老美技术先进

问题不在计算机模拟核爆，而在为了得到模拟核爆的数据是否不择手段，美国人在这一点上打擦边球是最厉害的，除了公然违反国际条约进行核试验以外，就数美国的亚临界核试验的性质最为恶劣了

不过，从大方面讲，无所谓，美国人的主要目的还是验证核武器的安全性，至少他们公开的讲是这么说的，至少不像冷战时是以摧毁对方为目的的，不过这不代表不保持警惕。

对我们危险最大的就是美国人找到了纯聚变的方法，可以绕过原子弹制造聚变爆炸，这样的氢弹是可以绕过核裁军条约的，而条约总是比武器出现的慢。美国人可以绕过核试验条约，就一定会绕过核裁军条约，到时候我们讨论的就不是动力装甲对付高斯步枪了，而是核弹枪炮。

不交电费？没门！电费里附加个核聚变设施建设费，然后我们的电价又涨了。。。
