Stanford uni scientists have created a particle accelerator on a chip smaller than a grain of rice (albeit one that won't actually accelerate particles). The details are in heavyweight boffinry mag Nature, in a paper titled Demonstration of electron acceleration in a laser-driven dielectric microstructure. Particle acceleration …
Brilliant method there to put a particle accelerator on a chip!
We used to have particle accelerators in our living room and office. Then they were replaced with flat screens.
Cut it some SLAC
> First, you must get the electrons up to speed and then ramp up their energy using electric fields and a precisely engineered tube of ridges
That is because after a "suitably high" energy, the speed doesn't change much because of "that speed limit".
This wouldn't make an "atom smasher" either (no hadrons), but if you add:
1) An antielectron source
2) The calorimeters and other detector stuff
Should be a Kickstarter project.
Well, that cool
So what is next? I vote for a micro-fusion reactor. Any seconds?
Re: Well, that cool
Yes, the ultimate non-replaceable phone "battery" you won't worry about replacing. A power source that lasts for 5 years screen time would be good.
Why does a Smart phone battery go flat quickly? Screen is 80% of power consumption.
I wonder what you could do with a large 2D array of these "rice grain" accelerators?
Re: Well, that cool
"A time-machine microwave?"
Is that to reheat tomorrow's leftovers?
A Little Something for Us Tempunauts
Nicely done. "preheat" in that case, though.
x-ray generator on a roll
"more practical applications are portable x-ray generators, including those suitable for medical imaging, which is why everybody's favourite crazy-tech-funder DARPA is prominent on the list of backers"
Or is it just a cover for an XRAY GUN!!!!!
No, that would be a tartan blanket.
Is this to go with the matchstick-sized directional microphone that was announced the other day?
Ghostbusters backpacks for real?
Just remember to not cross the streams.
Fun as that would be, the more practical applications are portable x-ray generators,
How could portable x-ray generators be "not fun"?
You lack imagination...
So kind of a Smith Purcell generator in *reverse*
Except here we fire the electrons below the grating (or at least in between 2 gratings).
Let's factor this is a 100x more intense field strength than conventional accelerators.
That puts a similar capacity to existing accelerators 1/100 the size of existing ones.
So, wait...we are on the cusp of having portable devices that can accelerate particles to relativistic velocities? Am I the only one thinking
A) Particle-beam weapon (assuming you lase a channel in the atmosphere first)
B) This, if they don't lase a channel...
Congratulations to the scientists who developed this. A truly incredible advancement.
Amazing science and technology are being developed these days. Now if we could just make the same strides in human psychology. Specifically, ridding the world of "dangerous crazy".
Then who would Americans vote for?
(Actually, that goes for the rest of us too.)
Integrate with Google Glass and...
Moulded in Poly Styrene?
There is already an X-Ray source the size of a grain of rice. I worked on it about 10 years ago. Check out a company called Xoft to see what it can do.
Whoops, the yanks just ran out of wonga, the bailiffs have seized it.
A pair of custom hand DeLameters for me please.
Now I wonder if this works with Protons as well.
Trickier to get a source but if so you can now accelerate Electrons and Protons, which can give Neutrons.
Obvious uses. High efficiency compact X ray sources. IE 10-20x better than conventional X-ray tubes.
But the big one is desktop fusion.
Just a thought.
