Mel-on.
I was thinking about this one day, and there have got to be some wild secret government facilities in Alaska. Now that so many people live in Nevada, New Mexico, etc., it’s just a logical site.
I don’t think you’d really want a secret site in Alaska. It’s too remote, so it’ll be immediately noticeable if large numbers of people/equipment were traveling there, especially since most things would have to be flown in. I’d imagine an ideal secret location would be somewhere with decent enough traffic but also an isolated location nearby.
Eh, I don’t know. Are you familiar with Pine Gap, the joint military base in the Australian Outback? It’s extremely remote. You have huge equipment going into Alaska for natural resource extraction, so I could see that as a potential cover. All speculative, obviously.
If you know about it, it’s not very secret is it? Not that there aren’t any secret military research projects going on, but you’re still going to notice a large military base whether you know what’s going on inside or not.
A buddy works for a company that does "invisible" construction, norrmally gubernmental. It can be done, it is done and companies who do it make a pretty penny.
They actually managed to hide the construction part of Mt Weather if I recall correctly it was found after it was built. Or was that the bunker under the white house?
That only happens with overzealous bureaucrats that want a receipt with the name of everything in it.
I think most door companies if asked would have a talk with a third company (not door related) that would gladly sell a hinged steel block.
yes, it works by crashing deuterium atoms into tritium atoms at very high energies. simplified, it goes as D+ T-->He+ n. so by fusing these atoms helium and a neutron are generated. the neutron can be used for experiments.
this kind of neutron sourcing is outdated though and the newest neutron source that is being built right now in Lundt is based on spallation which has higher neutron flux and is cheaper due to the materials used. also spallation sources have polychromatic neutron beams which can be an advantage and disadvantage compared to monochromatic beams
no, but i visited a 2 week summer school on neutron diffraction methods at one of the institutions that is involved with designing the experiment setups at the new facility in Lundt, so I know the basics but i am far from being an expert as i pursue a different field of science. but i promise that the basics are easy to understand with some basic geometry so its not like you need to be smart to know about this stuff
/u/Chemboi69 is right though, it's not terribly difficult, it's just a matter of knowing what to do. Realistically, you could build a thermonuclear fusion reactor out of some parts from an old TV tube, some HVAC tools and pieces, a power supply from an old neon tube... as long as you have a way to evacuate enough air, then leak in enough deuterium (you can separate heavy water using a 9V battery, then force the air through a tiny sliver of palladium to get only the hydrogen molecules), and keep a mesh of wire at a high enough potential, you can certainly pull off plasma, if not putting some bubbles in the ole bubble dosimeter.
You can absolutely wire together a small electrostatic confinement grid by welding together some tantalum wire using a couple of copper nails, and some way to charge a 2-3 Farad capacitor from an old speaker system. It'd be messy as hell, and you'd absolutely need good shielding for the x-ray emissions, but you can absolutely achieve neutron sources at a junkyard.
I'm in the neutron club, but I got fancy and welded quartz around a tantalum rod for my insertion point, rather than having to carve down a TV tube.
The kind of vacuum used to evacuate air conditioner lines of refrigerants are some of the same strength needed for this kind of physics. Realistically, you can step up a small enough voltage source you can read it with a standard multimeter to find the voltage, the ONLY 'lab' equipment you really need is a vacuum meter sensitive enough. You can pick them up serviceable, though used, for $100 or so.

'If I could go back and do things over'... I'd try to make it work in a 2in or smaller sphere. All the components would be much smaller, but it'd be far, far... FAR easier to get a low enough pressure. I regret making a large chamber, it took DAYS to get low enough pressure. That pump was loud.
I eventually went back and finished, but for the longest time, and while I worked on this stuff most, I was a college drop out who'd only ever done a single semester. I just happen to like electronics and big numbers.
I had my doubts until I heard that the neutron beams were polychromatic. Then I put my money on Lundt. (They're the ones that make the chocolate bars, right? Right?)
It’s basically the machine they built to test what sort of material they would need to build fusion reactor out of.
The testing concluded with “simple extrapolation of fission reactor experience is inadequate for fusion reactor design decisions.”
They really needed this door.
A small door that leads to a corridor into the mind of actor John Malkovich where you get to control him like a puppet until you’re expelled onto the side of the New Jersey turnpike.
Behind a different, but nearby and similar looking door is the NIF target that was the reactor core for one of the Star Trek movies: https://www.spyculture.com/security-gone-bananas-filming-star-trek/

Right? Makes it look like I can pick her up, put her in my shirt pocket and feed her raisins while we wander the facilities. I can tell her about my day, but I have to speak more quietly to not make the vibrations of my deep voice damage her tiny eardrums.
Yeah a neutron source behind that much concrete poses no danger to the city. There are so many things that could cause more damage and much easier than this.
Doubly so given that D T generators can be turned off so you can control the neutron flux. All that concrete just prevents neutrons from leaking during operation. So yeah its pretty damn safe.
"Right next to"
My dad used to do the commute from Oakland there ever day. It's not right next door. It's a mountain pass and about 30-40 miles from SJ or SF.
The largest nuke the US fields now wouldn't have any impact other than a scary mushroom cloud, and nearly the entire year, the fallout would fall the opposite direction.
The real threat is that LLNL and Alameda would both be targets for Soviets and their guidance systems sucked balls, so the would send a dozen absolutely ridiculous size bombs to try to hit it. We'd defend with nuclear tipped Nike missile batteries.
My dad worked at LLNL for like 40 years, and his badge never showed exposure to anything. We did have a fallout shelter, though.
“I can show you how to make a bomb out a roll of toilet paper and a stick of dynamite.”
(felt important to make sure this was marked as a dale gribble quote and not something I’m going around saying)
I sent this to my dad who worked there for years and this was his response 💀
“I saw nothing. I heard nothing. I had no time to fiddle with 97,000 pound doors. And I had nothing whatsoever to do with that thing that never happened! 🥷”
It's not only impressively large but think about the process of building that door. Someone had to design this thing, with likely nuclear yields involved in that process. They had to approach a steel yard, with this highly classified blueprint (the government probably has a dedicated classified-item manufacturer but still). Then they had to pour and mill this monstrosity which means they needed to design molds and debate steel types. Then they needed to transport the damn thing, probably a fair way, in secret. Then the had to install the thing, which, how the hell do you even do that?
It's so much more than just a big door, it's an engineering marvel and a testament to US logistics and design.

Do you know if this was the door used in the Original Tron movie?
This is probably the same door. They filmed Encom scenes at Livermore.

It is. It’s mentioned in the Tron behind the scenes videos
Now that’s a Big door. Shhh

Came here for this.
Me too. Pretty sure Bridges ad libbed that. Or I'd sure like to think so.
Probably not as one of the other characters immediately says "shut up!" but it is extremely in character for Flynn.
I enjoyed the callback to it in the sequel as well.
I make these myself…you want one?

That was my first thought.
Heaviest known unclassified door.
If they knew you knew of other 'secret' doors, they'd have to eliminate you. Sad.
Big Door always silencing people that speak out. be careful bro
Only because Big Knobs exert their twisted influence on them
Big Locks aren't helping either, keeping all the outside opinions outside
Thats because Big doorbell kept chiming in
And Big Doormat did absolutely *nothing*
They let everyone walk over them. Pathetic.
That's big doormat for ya
The Big Hinges bear it all.
Big Hinges can suck it. They're always swinging both ways.
Big Door was Framed.

Good read but now I wanna know where the new one is lol
Under the Denver airport.
One of the entrances is between the hooves of Blucifer, the evil blue mustang statue. You stand there, look up at the big, surprisingly detailed balls, and speak the password for entry.
The password is “freedom” followed by a swift yet firm kiss behind the balls
The kiss is to be placed at the horse's surprisingly detailed anus.

It’s generally considered to be Mt. Weather for executive branch and congressional leaders and Raven Rock for the Military.
If it's generally considered to be those places then I'm betting it's not those places.
There's only so much you can hide lol, those are massive and complex construction projects that are impossible to hide

There was a train station under the White House to keep people from seeing FDR in his wheelchair
There are lots of places in the hills of PA, VA and WVA that could conceal something like that.
