Vacuum Tubes are BACK!

Everyone knows vacuum tubes are more resistant to EMP and all kinds of radiation and temperature. Their main problem was size, reliability, and power requirement. The Japanese have invented nano-sized vacuum tubes that solve all of these issues!

Why should I use this over a mosfet?

Uh, this is a vacuum mosfet if you want to think about it. Benefits listed in the article.

But could a vacuum computer run Linux?

It could run Gentoo at 1000x the speed.

Joking aside, would programing differ in any way, or could we use mostly the same software with this new hardware? And would it be faster than transistors? Because I can imagine some very expensive graphic card that uses nano vacuum tubes, and then the technology could spin off from that. Which would mean hardened electronics would be the standard even for civilians.

That article is a fucking joke, it's pure PR

The article theorizes:
Since there's essentially no gain for the radical increase in cost, I doubt consumers will ever see nano-tubes in their computers. Even if they did, it's still your standard transistor setup. Nothing would change at the fundamental level.


That's mostly what science "journalism" is for. Not that we really have an alternative because most if not all of these papers are locked behind expensive paywalls.

its basically a nano scale mossfeet/vagina tube hybrid. Has all the benefits of transistors, some benefits of vacuum tubes (radiation hardening and faster transmission).


It could make a terahertz cpu eventually. Current tech is stuck in the Ghz stage, temperature becomes a problem if you try to increase it. But vacuum tubes have less resistance heat and are more temperature tolerant.


Current transistors didnt exactly enter the civilian market for awhile either, only government is dumb enought o finance over-expensive new tech.

I never stopped using vacuum tubes.

Short Answer: Yes.

Long Answer:The point of 'Architectures' is to implement a plan on how a computer is to be built as a system (input -> output). This is what makes an ARM, an x86, a POWER, etc. How the system is implemented (which this scope is the microarchitecture, and below that scope, the logic). The kernel does not know what lies below the architecture and any elements of exposed microarchitecture. Since this are feild effect transistors, they could work in cmos topographies. Maybe not as simply as current VLSI, but could be layed out in a similar fashion.

Sorry, I meant:

Short answer: programming would not change. Even assembly languages would not change.

OK since no one wants to search through it, here is a list.

How they are similar:

How they are different:

Advantages/disadvantages:
>Why did vacuum tubes give way to solid-state electronics so many decades ago? The advantages of semiconductors include lower costs, much smaller size, superior lifetimes, efficiency, ruggedness, reliability, and consistency. Notwithstanding these advantages, when considered purely as a medium for transporting charge, vacuum wins over semiconductors. Electrons propagate freely through the nothingness of a vacuum, whereas they suffer from collisions with the atoms in a solid (a process called crystal-lattice scattering) this is partly what causes high temperatures. What’s more, a vacuum isn’t prone to the kind of radiation damage including thermal that plagues semiconductors, and it produces less noise and distortion than solid-state materials.

Reason for transistor rule up until now:

Why this is important:
We’ve been working to develop yet another candidate to replace the MOSFET, one that researchers have been dabbling with off and on for many years: the vacuum-channel transistor. It’s the result of a marriage between traditional vacuum-tube technology and modern semiconductor-fabrication techniques. This curious hybrid combines the best aspects of vacuum tubes and transistors and can be made as small and as cheap as any solid-state device. Indeed, making them small is what eliminates the well-known drawbacks of vacuum tubes.
In a vacuum tube, an electric filament, similar to the filament in an incandescent lightbulb, is used to heat the cathode sufficiently for it to emit electrons. This is why vacuum tubes need time to warm up and why they consume so much power. It’s also why they frequently burn out (often as a result of a minuscule leak in the tube’s glass envelope). But vacuum-channel transistors don’t need a filament or hot cathode. If the device is made small enough, the electric field across it is sufficient to draw electrons from the source by a process known as field emission. Eliminating the power-sapping heating element reduces the area each device takes up on a chip and makes this new kind of transistor energy efficient.
Another weak point of tubes is that they must maintain a high vacuum, typically a thousandth or so of atmospheric pressure, to avoid collisions between electrons and gas molecules. Under such low pressure, the electric field causes positive ions generated from the residual gas in a tube to accelerate and bombard the cathode, creating sharp, nanometer-scale protrusions, which degrade and, ultimately, destroy it. What if the distance between cathode and anode were less than the average distance an electron travels before hitting a gas molecule, a distance known as the mean free path? Then you wouldn’t have to worry about collisions between electrons and gas molecules. For example, the mean free path of electrons in air under normal atmospheric pressure is about 200 nanometers, which on the scale of today’s transistors is pretty large. Use helium instead of air and the mean free path goes up to about 1 micrometer. That means an electron traveling across, say, a 100-nm gap bathed in helium would have only about a 10 percent probability of colliding with the gas. Make the gap smaller still and the chance of collision diminishes further.
But even with a low probability of hitting, many electrons are still going to collide with gas molecules. If the impact knocks a bound electron from the gas molecule, it will become a positively charged ion, which means that the electric field will send it flying toward the cathode. Under the bombardment of all those positive ions, cathodes degrade. So you really want to avoid this as much as possible.
Fortunately, if you keep the voltage low, the electrons will never acquire enough energy to ionize helium. So if the dimensions of the vacuum transistor are substantially smaller than the mean free path of electrons (which is not hard to arrange), and the working voltage is low enough (not difficult either), the device can operate just fine at atmospheric pressure.
That is, you don’t, in fact, need to maintain any sort of vacuum at all for what is nominally a miniaturized piece of “vacuum” electronics!
But how do you turn this new kind of transistor on and off? With a triode vacuum tube, you control the current flowing through it by varying the voltage applied to the grid—a meshlike electrode situated between the cathode and the anode. Positioning the grid close to the cathode enhances the grid’s electrostatic control, although that close positioning tends to increase the amount of current flowing into the grid. Ideally, no current would ever flow into the grid, because it wastes energy and can even cause the tube to malfunction. But in practice there’s always a little grid current. To avoid such problems, we control current flow in our vacuum-channel transistor just as it’s done in ordinary MOSFETs, using a gate electrode that has an insulating dielectric material (silicon dioxide) separating it from the current channel. The dielectric insulator transfers the electric field where it’s needed while preventing the flow of current into the gate.
So you see, the vacuum-channel transistor isn’t at all complicated. Indeed, it operates much more simply than any of the transistor varieties that came before it.
Our very first effort to fashion a prototype produced a device that could operate at 460 gigahertz—roughly 10 times as fast as the best silicon transistor can manage.


That's neat.

So can we make an EMP-proof machine using vacuum transistors and fibre optics? Is the next step then to EMP the world and become kings?

All of a sudden I remembered the caste of academics/priests tending a long dead AI from the novel The Postman.

i don't think a vacuum tube would do shit against an EMP. EM waves don't need a medium to travel through like sound waves. they propagate through space itself. otherwise we wouldn't be able to detect shit like gamma bursts out in the vacuum of space. honestly, if you're worried about an EMP, you'd be better off wrapping your shit with aluminum foil for a makeshift Faraday cage.

It's not that a vacuum would block EMP in some way, because you're correct - EM waves don't need a medium to travel through. What makes vacuum tubes resistant to EMP is that a vacuum is empty; there's nothing in there for an EMP to fuck with.

You don't understand.
EMP kills systems by causing a power surge. Tubes have several orders of magnitude larger voltage tolerances, so you need a proportionally stronger EMP to destroy them (although they'd probably still crash and need to be reset).

It's called lead plating.

OK keep in mind I'm a biologist not an engineer, so this is all third hand knowledge:

Transistors work because the gate (silicon oxide) can prevent transmission of electrons at some voltages, but stop them at others. EMP overcharges the gate and turns the transistor into a plain wire, and then pumps so much electrons through that the gate is welded permanently open.

However in a vacuum tube, the vacuum plays part of the gating purpose, and vacuum can't be destroyed or welded. So although an EMP might force the gate open temporarily in a vacuum transistor, it can't permanently weld the gate opened. This means that a computer running VCT might suffer data loss by an EMP, but it wouldn't be permanently broken.

Also the amount of volts needed to force the gate open in a transistor is ~1V, and in a vacuum tube is ~10V, so there is an inherent resistance there as well. But that difference will disappear in more efficient VCTs.

Military vehicles need lines to the outside in the form of communication antennas, radar dishes, sensors etc…. they can't be faraday shielded.


This is how you lost the war.

What radical increase in cost? It's the same process as transistor microfabrication, therefore it costs the same.

What a retarded post. Why are you hiding your flag, coward?

Mind sharing exactly what is retarded about it?

Everything, starting with his "emp"-understanding of it being like in videogames.

Electromagnetic pulse is a burst of very high energy, conversely high frequency, photons. It's kinda its thing, it's not a "pulse" if it's low frequency. A photon striking an object imparts its energy onto material's electrons, in form of excitation or momentum. In non-conductive materials, electrons are strongly bound to their protons, so all of that energy has to be either scattered by re-radiation, or dissipated as heat. In conductive materials, electrons are free to move around, so photons' energy is turned into electrons' momentum, i.e. electric current. This is how antennas work. Which also means that any and all metal objects antennas and can generate electric current from electromagnetic radiation. So what happens when an EMP strikes a conductor, is that there's a shitload of current induced in the conductor. If this current can't flow freely, electrons build up on one end of the conductor, and the electric potential increases until it reaches breakdown voltage and there's an arc discharge between it and the other object. In a microelectronics, that would be between source and drain ends on the transistor gates. And the thing with transistors is, the breakdown arc leaves permanent low-resistance path in the semiconductor, shorting it open, thereby destroying it.

That is in no discrepancy with what hiddenflag said.

Maybe he thinks he can get away with bullying me because I said I'm not an engineer?

tl;dr, try not to be such a boring cunt next time.

Tell me about all those iiieeeemmmpiiiiii weapons that destroy all the current military equipment, chaim. tell me why everyone needs to buy meme-tubes right now.

EMP interference is generally disruptive or damaging to electronic equipment, and at higher energy levels a powerful EMP event such as a lightning strike can damage physical objects such as buildings and aircraft structures. The management of EMP effects is an important branch of electromagnetic compatibility (EMC) engineering.

Weapons have been developed to deliver the damaging effects of high-energy EMP.

>muh (((official))) demographics
America even counts blue eyes blonde ethnic Spanish people as nonwhites.
Germany counts decimeter-diameter head Somalians as native German Vikings.

Please don't crap up the thread.

Use sci-hub.io strelok.

Wew. Maybe Moore's Law becomes true again.

No it doesn't retard, it literally counts, Arabs, other semites, Iranians and North Africans "non-hispanic whites" (maybe some Indians too, not sure) and mud-brown spics as "hispanic whites". Please give me a source of a single blonde-haired, blue-eyed Spaniard being recorded as "non-white hispanic".

That 81% figure is specifically for ethnic German whites with no immigrant background, similar to the "white British" category we have.

Maybe the yankee doodles should stop replying to every post with "whiter than you, muhammad"

You're confusing our law enforcement with the census.
The niggers are wrangled by the executive and thrown in prison by judicial, the census itself is partly legislative but mostly exists outside the three branch system because it's mandated by the constitution.
Police have nigger quotas they can't go over, census is just retarded.

The fact that "hispanic" disqualifies someone from being white, when 47% of hispanics in general are white as the driven snow, is a fucking joke. Mexican government gives preferential treatment to mixed and natives, and even so their genetic studies show mexico is about 43% white, But when they cross the border they disappear.

They had 3 million turks in 2009.
Turks have a higher than replacement fertility rate.
From 2009 to 2016 many more turks immigrated.
In 2016 germans only had 2.7 million turks.

This is how you know their census is bullshit.


Wow you're right they kind of look like ancient british.

It'd take some R&D though before they become commercially viable which of course is bad unless (((Intel)))-aviv does it.
Wafer yield might also be too low for mass manufacture with current processes, it's one of the reasons MRAM hasn't seen any widespread use as of now.

Why would wafer yield be lower? Vacuum gates have the same physical layout as transistor gates except they don't have a semiconductor layer.

So they are more resistant to heat and electomagnetic pulses, but what about acceleration? Because if they can deal with G forces too, then this will also lead to better electronics and fuses for missiles and shells.

Why would they have issues with acceleration? Just due to the fragile nature of the tube?

I wanted to imply with the structure of my sentence that I inquire if they are more resistant to acceleration that semiconductors, or not.

Nigger what?

It makes sense to me. I don't know the answer however.

He wants to know which is more resistant to acceleration, classical transistors or vacuum transistors. The answer is that either of those can take over 500,000g… transistors aren't the components that fail under g stress, welds and larger things are.
