PARTICLE ACCELERATOR... ON A CHIP

When you think of a particle accelerator, you usually think of some giant cyclotron with heavy-duty equipment in a massive mad-science lab. But scientists now believe they can create particle accelerators that can fit on a chip smaller than a penny. The device uses lasers and dielectrics instead of electric fields and metal. The conventional accelerators are limited by the peak fields the metallic surfaces can withstand. Dielectric materials can withstand much higher fields but, of course, don't conduct electricity.

Physicists fabricated a 225 nanometers wide channel in various sizes up to 0.5 millimeters long. An electron beam moves through the channel. Very short infrared laser pulses on top of the channels accelerate the electrons down it using tiny silicon pillars.

The electron beam entered the channel at 28,400 electron volts. They exited at 40,700 electron volts, a substantial increase. The tiny pillars are only two microns high, so fabrication is tricky. Possible applications include cancer treatment, electron microscopy, and the creation of compact high-energy lasers.

The nanofabrication required for these devices won't be in our garage any time soon. However, we hope this might lead to a new class of devices that we can use to build exciting new things. After all, remember how it used to be hard to build things using a laser?

There might actually be a useful application. If they could couple lasers that pulse basically a highly charged particle (wave) that can go through the body
then they could focus them where there's an inoperable brain tumor. Basically they could cook the tumor so the body can flush it or at least keep it from growing.
Outside of something like that, it might just be a toy for them to play with.

They already have devices that can do that. Making them 'smaller' won't make much difference. Problem is that they aren't 'smart' particles, which only destroy the cancer. Every cancer treatment we have, also damages healthy tissue. Most will heal over time. Every cell in the path of the electron 'beam' will be damaged/destroyed, just as the cancer cells. One surviving cancer cell, makes it likely the tumor will reform. That's why they always follow up with chemotherapy. Which, is literally poison therapy. Would doubt it's killed as many as it's saved. The chemotherapy never listed as a contributing factor, for liability reasons. Beside, the dead person signed forms...

Always thought CRTs, tube-type TVs/monitors were particle accelerators. An electron beam is scanned across a phosphor coated screen.

Harvey, I always thought the CRT was an anode and not a cathode with the phosphor screen being the cathode.

A CRT is an electronic vacuum tube (with a funny shape). It has both a cathode and an anode, as well as grids and screens (not the part you watch video on).

In a circuit, the cathode is located in the neck of the tube, with the the bell end being the anode (typically 27kV). Beam focusing electrodes also exist in this tube to form the particles (electrons) into a tight beam. The beam is deflected by a magnetic field (coming from a set of coils on the neck right up against the bell, and called a 'yoke').

The anode is located in the bell, but is NOT the visible screen covered with phosphors. It is located in the BACK of the bell.

The high speed electrons do have mass (like any particle). The don't go directly for the anode, but are moving so fast they hit the phosphors first. The high voltage on the anode is what gives them their speed though.

X ray machines also use a vacuum tube, accelerating electrons in much the same way. Instead of using phosphors that generate visible light, the target in an X ray tube generates X rays.

Electronic tubes are still used today in common applications. One such that is probably in your home right now is a microwave oven.

Swan, learn the difference between 1 eV and 1 V.
The first is a unit of energy. The second is energy per coulomb of charge (electrons).

The eV is a unit of energy equal to the work required to move a single electron between two points having a potential difference of 1 volt.

A volt is energy per coulomb of charge (6.24 x 10^18 electrons) required to move the charge between two points. Units are Joules/coulomb.

1 eV = 1.602 x 10^-19 Joules.

And since I doubt you know math Swanee (religious teacher. specifically : a senior member of a religious order) if you multiply 1.602 x 10 = 16.02. Then because it's to the negative 19th power you simply move the decimal 19 places to the left so it looks like
0.0000000000000000001602. And then when multiplied by 40, 000 or 4 x 10^4 then you can simply subtract the 10^4 from the 10-19 so it 1.602 x 10^15 or
0.00000000000001602.
See how easy that is Swanee if you would've just read the article? Basically what they're sending through the nanotube is wave energy such as a microwave. They've been experimenting with using microwaves for flipping qubits (time crystals) in quantum computers. And with such a small wire, who knows it might be for something like a quantum computer. What do you think? Could having the voltage change in a nanotube improve the efficiency of quantum computing?

Ummm, this thread is about a particle accelerator on a chip. We've discussed quantum computers in here and it was Harvey who started that thread like he did this one. Myself, I just wondered when the particle became more energetic if that had to do with some property of the nanotube and if not then what was responsible for the increase in eVs?

The anode is located in the bell, but is NOT the visible screen covered with phosphors. It is located in the BACK of the bell.

The high speed electrons do have mass (like any particle). The don't go directly for the anode, but are moving so fast they hit the phosphors first. The high voltage on the anode is what gives them their speed though.

X ray machines also use a vacuum tube, accelerating electrons in much the same way. Instead of using phosphors that generate visible light, the target in an X ray tube generates X rays.

Electronic tubes are still used today in common applications. One such that is probably in your home right now is a microwave oven.

When you think of a particle accelerator, you usually think of some giant cyclotron with heavy-duty equipment in a massive mad-science lab. But scientists now believe they can create particle accelerators that can fit on a chip smaller than a penny. The device uses lasers and dielectrics instead of electric fields and metal. The conventional accelerators are limited by the peak fields the metallic surfaces can withstand. Dielectric materials can withstand much higher fields but, of course, don't conduct electricity.

Physicists fabricated a 225 nanometers wide channel in various sizes up to 0.5 millimeters long. An electron beam moves through the channel. Very short infrared laser pulses on top of the channels accelerate the electrons down it using tiny silicon pillars.

The electron beam entered the channel at 28,400 electron volts. They exited at 40,700 electron volts, a substantial increase. The tiny pillars are only two microns high, so fabrication is tricky. Possible applications include cancer treatment, electron microscopy, and the creation of compact high-energy lasers.

The nanofabrication required for these devices won't be in our garage any time soon. However, we hope this might lead to a new class of devices that we can use to build exciting new things. After all, remember how it used to be hard to build things using a laser?

Think this is just a can-we-do-it, with little potential for anything useful/practical. A whole lot of energy, external equipment needed, for very low power output

40000 volts would melt a microchip in about .00001 microseconds

Admit it, you know nothing...

I know that 40000 volts can go thru a cable but not the near atom wide wires in a chip.

There might actually be a useful application. If they could couple lasers that pulse basically a highly charged particle (wave) that can go through the body
then they could focus them where there's an inoperable brain tumor. Basically they could cook the tumor so the body can flush it or at least keep it from growing.
Outside of something like that, it might just be a toy for them to play with.

They already have devices that can do that. Making them 'smaller' won't make much difference. Problem is that they aren't 'smart' particles, which only destroy the cancer. Every cancer treatment we have, also damages healthy tissue. Most will heal over time. Every cell in the path of the electron 'beam' will be damaged/destroyed, just as the cancer cells. One surviving cancer cell, makes it likely the tumor will reform. That's why they always follow up with chemotherapy. Which, is literally poison therapy. Would doubt it's killed as many as it's saved. The chemotherapy never listed as a contributing factor, for liability reasons. Beside, the dead person signed forms...

Always thought CRTs, tube-type TVs/monitors were particle accelerators. An electron beam is scanned across a phosphor coated screen.

Harvey, I always thought the CRT was an anode and not a cathode with the phosphor screen being the cathode.

A CRT is an electronic vacuum tube (with a funny shape). It has both a cathode and an anode, as well as grids and screens (not the part you watch video on).

In a circuit, the cathode is located in the neck of the tube, with the the bell end being the anode (typically 27kV). Beam focusing electrodes also exist in this tube to form the particles (electrons) into a tight beam. The beam is deflected by a magnetic field (coming from a set of coils on the neck right up against the bell, and called a 'yoke').

The anode is located in the bell, but is NOT the visible screen covered with phosphors. It is located in the BACK of the bell.

40kv is the potential, but you need amps (current) for the electrons to flow. The wire is gauged for how much current flows through the chip. Computer chips are usually low power, so only need fine gauge wire. But, they don't have to even use wire... Lot of consumer electronics use COB chips (circuit on board). It's a black blob on the circuit board. Pisses me off too...

Sure, you can burn up any component by applying more power than they were designed to handle.

What speed are the particles on the chip accelerated too.

Two beams of protons will each travel at a maximum energy of 7 TeV (tera-electronvolt), corresponding to head-to-head collisions of 14 TeV.

So how does one measure 99% the speed of light on a thumbnail where the particle only travels 0 miles, 0 feet, 0 inches and even 0 cm?

With a Hadron collider you need glass about 4 feet thick to contain the radiation.
With the chip, if the nanotube increase the eV (electron voltage) of the wave then when they say "accelerator", does eV 25,000 to eV40,000 have anything to do with E = hv?

Is that all you have? No science and no math? Weren't you laughing about something going from 25,000 eV to 40,000 eV? You know? The chip that Harvey posted about. And now you want to discuss CERN but only it's features?
You didn't know what eV stood for and now you want me to explain something else to you? I'm not the Swanee am I? Nope, that's you. And do some colliders use glass? Yep. Scale or size of the particle accelerator does matter. If glass 4 feet thick acts as a barrier for radiation, is that less expensive than basically creating a torus and then having metal shielding?

p.s., And Swanee, I never said CERN. Why you mentioned that when discussing particle accelerators was your decision, it's not the only one. And as you mentioned is it is about having the power.

I think when you don't understand 1 eV = 1.60218 x 10^-19 Joules is the real problem. With 1.60218e-19 the e means x 10^, my bad.
Then 25,000 eV = 25 x 1.60218e-19 = 4.00545e-15. Multiply that by 1.6 to equal
40,000 eVs is 6.4087264e-15. I think it's important for you to understand the mistake that you made. Then when we discuss something like this then you'll know what we're talking about.
If you consider 1 eV = 1.60218 x 10^-19 Joules and Planck's constant is
h = 6.6 × 10^−34 J · s. Planck's constant is 1 quanta of light. If we divide 1 eV by
Planck's constant then we'll know how "many" quanta of light it takes to generate in 1 eV. That number/value is 2.427545455e14. That's the equivalent quanta of light for the 25,000 eVs input into the nanotube. See how "small" your mistake was?
With what you want to discuss should have its own thread because Harvey was discussing an accelerator in a chip. It's like if I were to say 28 inches of water when referring to 28 cubic inches of water you'd say I'm stupid when you would only be attacking me because as you say that is how you teach.
Yet you are not aware of what 30 inches of mercury refers to. Please explain what 30 inches of mercury is. I gave you the answer so this should be an easy one for you. If not then show some math. Oops, I did it again; https://www.youtube.com/watch?v=CduA0TULnow

Until this thread, he had only heard of the huge particle accelerator projects. Totally clueless that he's used them all his life...
