NIF Back on Track
High-Laser-Energy Shot Puts NIF Back on Track Toward Ignition
From an idea, an unclear concept 15 years ago to a 100-square acre, flawlessly operating instrument assimilating amazing new technologies from material, to modelling to controls...
1.8MJ of blue light.. 500TW every 4 hours on a 3 mm target... Wow.
Brilliant.
24 beamlines 192 beams, adaptive optics, 5 MJ of capacitors, amazing 9000 pcs of 40cm x40cm Nd glass, meter-long 9000 flashlamps, literally millions of optics... Cleanest large surfaces ever produced, 1000s of times better than in wafer production.
A reliable 4K target system in a shielded 10m diameter vacuum sphere. DT targets regularly meeting exacting standards. Calibrated diagnostics systems to determine performance. Models to support interpretation.
All to the highest seismic standards, every system with a safety note, checked and rechecked.
Truly a magnificent lifetime achievemnt. Something Haussman dreamed of when he hired Emmett. What Paisner, Simmons, Hurley and Frietag strove for in setting high scientific and engineering standards. What Trenholme's team predicted.
Over 1000 labbies contributed years of their lives and many, many late nights.
Remarkable. Unprecedented. The damn thing works...it regularly meets its design specs.
There is no such thing as a "square acre." Your credibility was ruined early on in your post. The rest you got out of an old LLNL media piece. You understand nothing of what you posted. But hey, uneducated enthusiasm is ok.

Let the ship sail, discoveries await. One does not need to understand one only needs to believe.
This shows that the NIF design and the lasers in particular are, unfortunately, just below the power and energy needed to achieve reliable ignition. Its too bad they didn't target a design with about 2x the laser energy. Now their only hope is to make perfect capsules and optimize the hell out of the optical system and hope for the best. By the end of the decade they hope to increase laser energy a whopping 5-10%??
Oh, and you can square an acre, but I'm not sure what it means.
That marks the official end of the Sandia Z-machine fusion program. Absolutely no chance of a new pulsed power machine. Time for Sandia to pull the plug on that program and invest in more promising ventures.
The “Lux” guy really annoys me although I get what he’s saying. By the way, NIF has 500 MJ of capacitors, not 5 MJ, which is a huge feat in itself. Technically NIF is the biggest pulsed power facility ever constructed.

“Ignition” - you keep using that word. I do not think it means what you think it means…
NIF über alles!
Remarkable. Fantastic.

Thanks for the confirmation Al.
"FIAT LUX" is fulfilled.
Now on to discoveries...

OK, so it's a religion for you. Got it.

Nothing will ever beat the Sandia Z, so you better learn to cope.
NIF is more on track than you think. Stay tuned for details.

Take a guess which machine wins the 2023 Noble prize, stay tuned.
"Nobel" You aren't the winner.
