NIF delivers 500 terawatts to fusion target

Livermore, CA--On July 5, the Lawrence Livermore National Laboratory's National Ignition Facility (NIF) achieved a historic record-breaking laser shot. The NIF laser system of 192 beams delivered more than 500 trillion watts (terawatts or TW) of peak power and 1.85 megajoules (MJ) of ultraviolet laser light to its target. 500 TW is 1,000 times more power than the United States uses at any instant in time, and 1.85 MJ of energy is about 100 times what any other laser regularly produces today.

Combining extreme levels of energy and peak power on a target in the NIF is a critical requirement for achieving one of physics' grand challenges--igniting hydrogen fusion fuel in the laboratory and producing more energy than that supplied to the target. In the historic test, NIF's 192 lasers fired within a few trillionths of a second of each other onto a 2 mm diameter target. The total energy matched the amount requested by shot managers to within better than 1%. In addition, the beam-to-beam uniformity was within 1%, making NIF not only the highest energy laser of its kind but the most precise and reproducible, according to LLNL. "NIF is becoming everything scientists planned when it was conceived over two decades ago," NIF director Edward Moses said. "It is fully operational, and scientists are taking important steps toward achieving ignition and providing experimental access to user communities for national security, basic science and the quest for clean fusion energy."

The user community agrees. "The 500 TW shot is an extraordinary accomplishment by the NIF Team, creating unprecedented conditions in the laboratory that hitherto only existed deep in stellar interiors," said Dr. Richard Petrasso, senior research scientist and division head of high energy density physics at the Massachusetts Institute of Technology.

Bad idea if the writers wanted to do any conceivable real-world physics. This is what happens.

It is! Just like 40 years ago.

>> “Nuclear fusion that much closer.” <<

.
Not too sure of that now.

I did the layout when they were converting from “Nova” to the “Shiva” laser system there, back in the ‘80s. At that time they had estimated that about one millionth of that much power was going to do the job ‘soon.’

What next? They’ll be dimming the lights of the whole Bay Area when they reach the next level from this. (if we don’t just go broke first)

They don’t appear to be any closer than the late Kip Seagal was when he started with an Army surplus laser and his own bank account in Ann Arbor in the ‘70s.

A major weapons system. Combine it with a satellite mirror and GPS and you can wipe out anything on earth.

“500 TW is 1,000 times more power than the United States uses at any instant in time.” So where did all of this energy needed for this reseach come from? Take a guess. The logical conclusion and premise is never (almost always) considered in the original article. This is nonsense.

Wow. Then why do we have power outages? Why are we pursuing solar and wind if we can release that much power? Why aren't we tapping this incredible source?

It's a matter of units.

500TW is more power than the US uses at any instant.

They load up capacitors and discharge them quickly. It's not 500TW/h.

Power measurements depend on the discharge time.

That's what the author left out. Also why culinary school is better than journalism school.

The total laser energy was 1.85 megajoules. That’s a little more than a half kilowatt hour.

I was going to DVC in the early 80s and knew one of the machinists who ran Diamond Turning Lathe III to make the mirrors for Shiva. I saw those capacitor banks too. At that time there were the laser guys and the magnetic bottle guys. It was the latter that were the real power hogs... 900MW if I recall correctly.

Interestingly, not far away they were installing a laundromat of hard drives for "global warming research."

If it ain't usable, it ain't power, unless it's heat.

Sorry about the sloppy formulation. Culinary school only covered so much...

It only lasts a few billionths of a second, with the goal being to ignite a fusion reaction.

Thank you. But someone still needs to learn how to write an article, and it is not Freepers.

I’m curious to know if the containment vessel is pressurized, and if so, to what degree?

Good one!

I remember a former editor of a major national newspaper (can’t remember which one and can’t remember his name) speaking to the Journalism Department at Duke. He advised the students to get a broad education and not stay within the confines of the Journalism school.

” - - - This is nonsense.”

Agreed. However, we live in an age of Junk Science, and razamatazz “discoveries” such as this will feed “cold fusion” rumors for years.

BTW, has anybody figured out the safe lab distance one needs to be if there really was, (thanks to Kenyan GOVERNMENT RESEARCH, of course), Cold Fusion?

Can you imagine what might have been done with all the capability represented in those projects in terms of people, machines, and money? It’s staggering.

Just google it: (1.85 megajoules) / (500 terawatts) = 3.7 nanoseconds. Or about 1/270,270,270th of a second.

My mind would wander in that realm every time I entered the grounds of LRL.

Countless monstrous chunks of stainless steel tunnel dotted with flanged openings, costing millions each to manufacture, were at the time scattered on the pavement like a giant wrecking yard, clogging the path we had to take to the laser project, which was among the least developed areas on the campus.

Cool. How long is one instance of time?
