>>16546220
Nope. It was very dirty. The cleanest was Tsar Bomba with 97% of its yield coming from fusion.

>>16546218
>cleanest
fusion produces a lot of neutron flux, which neutron activates most materials causing them to become radioactive
fusion energy plants will have to periodically replace all of the highly radioactive parts that have degraded due to neutron dislocation
it ain't as clean as popularly believed

>>16546264
>97% > 99.01%
Kek.

>>16546317
77% of the yield of Ivy Mike was just from the fast fission of the tamper.

>>16546358
Kek.

That would be Ripple II from the Housatonic test during Operation Dominic. It yielded about 10 megatons with only a 10 kt fission primary or about 99.9% pure fusion. It was an unconventional design compared to the standard Teller-Ulam configuration. Apparently, it was so efficient that it didn't require a fission sparkplug.

I thought "fusion" bombs are really just fission bombs where the fusion only adds additional neutrons to accelrate and make the fission a much higher percentage of the energy than without the fusion neurton boost.

Pure fusion nukes are a reality and the most closely guarded nuclear secret

>>16547313
it's the other way around. the fission stage in a fusion bomb is only to produce the required temperature and pressure to set off the fusion stage.

>>16546491
Interestingly, the Kinglet/Ripple II device was already tested earlier and fizzled.

Both exist; former are called boosted fission bombs, while latter are (multistage) thermonuclear bombs

Tsar Bomba

heh heh

No uranium tamper?

Aren't fusion bombs very expensive to maintain due to the tritium half life? Also doesn't the radioactive hydrogen need to be kept in a compressed liquid state the whole time?

>>16547464
You mean isomer warheads? Wait until you find out about the Dugway Zapper, our positronium particle beam via a polariton driven gamma ray laser

>>16552430
There are solid hydrides and much better neutron flux moderation

>>16552068
No, it didn't use any fissile tamper, and it was certainly not an ordinary one. Yet, it was theorized to break the 6 kt/kg Taylor limit, with a predicted yield ratio of 12–18 kt/kg.

Ivy Mike, feel free to ignore the russian bots

>>16552430
The tritium in a fusion bomb is bred from (stable) lithium-6 during the explosion

>>16553271
Intredasting, haven't seen details of this before

>>16553271
>such as lead or uranium
so lead?

>>16554264
Who knows? But most sources suggest it didn't have any fissionable tamper like depleted uranium or thorium. It could have been any high-Z material, like lead or even gold, as used in the W71 warhead.

>>16552760
Isomer controversy was an actual oh shit moment in terms of it being something that should not exist as far as the public is aware. It's also misdirection; the technical prowess required to properly implement that concept in a weapon is a distraction being more needlessly complex than pure fusion. With pure fusion, the path to gamma ray lasers also becomes simplified and convoluted solutions are not required. Don't get distracted fren.

>>16546491
I hate people who talk like this pseud in pic. you aren't even dumbing it down for laymen. you are uneducated and trying to sound like you know what you are talking about after reading the wikipedia article or asking ChatGPT

>>16554264
Not necessarily, as the modulator layer are said to be exaggerated in the drawing, and implied to be very thin. It is possible that benefits of using depleted uranium over the much lighter lead may outweigh any negative aspects. It could even make the bomb cleaner due to more efficient fusion stage

Bros, I really wanna build a thermonuclear bomb now, just for the hell of it. Who's in?

>>16555462
Those are not very useful.
Total mind control is far more practical.

>>16546218
the sun

>>16556857
The Sun is a fusion reactor.
Not a thermonuclear explosion.

>>16546218
>making it the cleanest in terms of energy production
Definitely the case.

Or, plasmonic compression mechanisms are the way forward towards a gamma ray laser. I'm of the mindset that we already have developed this in the late 90's or early 2000's. Unironically, I thought this was directional IGE from a hafnium isomer at first until I found some old posts from on the interwebs from 2004 and then found pic related.
>What happens to the wavelength of your probe beam?
Intuitively, one would imagine a proportional decrease in the wavelength, i.e. hellacious blueshift. Also, a use case for isomers was definitely "discovered". JASON did a study at some university in Japan (can't remember the name right now), which resulted in a classified dissertation specifically for hafnium isomers. As far as gamma ray lasers and collimated beams of bound state positronium, there is a guy at UC Riverside (Allen P Mill Jr.) that is attempting to do it in reverse, i.e. an positronium annihilation driven gamma ray laser. The work by Hau and Ketterle is especially odd because there is no patents for any commercial applications of their work, despite this having enormous implications for photonic computing/data links, lithography below the diffraction limit, etc. There is just a patent on the electromagnetically induced transparency trap shared between Harvard and MIT. Also odd, both the Nobel work by Ketterle in 1994 and all of the stopped/slow light and superluminal propagation experiments were directly funded by the Office of Naval Research, and Hau had a grad student attached to her work (Zachary Dutton) who worked for Raytheon and still does.

>>16560038
To add, the "no patents" implication is that this was an overtly defense oriented research project that did indeed result in actual patents, but said patents were subject to a Group220 gag. Right after her publications in Nature, Hau was given some cushy civilian defense research position and which probably coincided with a Type 2 or 3 Secrecy Order and maybe an Atomic Energy Act review.
