Table-top Particle Accelerator Created
holy_calamity writes "French physicists have built a desktop particle accelerator. It uses a pair of laser beams to precisely control the acceleration of electrons within a plasma. It has the power of a device that usually takes up a whole room and could lead to new medical treatments. They don't mention the potential for experiments like 'what happens if I put my lunch in front of a 300 megaelectronvolt beam?'"
*sigh*

Oh, nevermind....
Sometimes boldness is in fashion. Sometimes only the brave will be bold.
'what happens if I put my lunch in front of a 300 megaelectronvolt beam?'
Nothing you can see, because that's ~ 4e-11 J.
Lunch is all well and good, but I'm still waiting for an investigation into the device's popcorn-popping capabilities.

I want tables with frickin' lasers on their heads. I apologize.
the mods may say you posted flamebait, but to me it's a flame that warms my heart. rock on, brother! --chebucto
At last, I've found the perfect Christmas gift for my evil genius cousin!

These guys never heard of air hockey?
with LCDs!
I can see it now...
Boss: "What is that on your desk?"
Me: "A particle accelerator."
Boss: "OK, next question... Why?"
Me: "Because I can."

Whatever you do, don't cross the streams!

:P
Some egghead before or during World War II had an egg in his pocket when working around microwave beams when the egg decided to go pop. The device is called a microwave oven and sits on the kitchen counter. I got mine for free when I signed for a one-year lease on my apartment.
Please Santa can I have a Particle Accelerator? I've been good!
Always be polite.
Press the button to find a new particle. Bonus points if you find a Graviton.
This has been done already, just with really really really big desktops.

An unlicensed nuclear accelerator?

And don't use the term 'egghead'. It's origin is Nazi brown-shirts referring to how the skulls of intellectuals shatter when they hit the ground. (Or something equally violent.) We have enough anti-intellectualism in this country already.

Hey mom, watch me accelerate Timmy to 0.9c!

BTW, don't use the term 'egghead'. That anti-intellectual term comes from Nazi brownshirts referring to how easily intellectual's heads shattered, or something equally violent. We have enough anti-intellectualism in this country already. Just look at those damn Geico commercials.
(Seriously. The 'modern' humans are assholes who can mock or outshout the cavemen but that's all... and don't feel any shame about it. The 'cavemen' are the ones who clearly articulate their opinion and accomplishments.)

That's not true. The term dates back to the first decade of the 20th C. as slang for "bald". Chicago newspapermen picked up on the word and started using it to mean someone with intellectual pretensions and the term gained widespread popularization in 1952 when New York Herald Tribune columnist Stewart Alsop used it to refer to the presidential campaign of Adlai Stevenson.
isnt this just a wakefield accelerator?isnt that old news?unless im wrong ive read about this bout a year ago in sci.am.
300 MeV may be 4e-11 J, but that's not the relevant figure. 300 MeV refers to the energy of a single electron in the beam. The beam itself, however, contains many, many electrons, not to mention the energy in the lasers and plasma producing the beam.
like every software project I took part in.

IANAQM (Quantum Mechanic) but I do not recall the discovery announcement for this hadron(?).
There is no right to feel safe thru security vaudeville at the expense of everyone's freedom, privacy and tax money.
I accelerate particles every morning when I fire one out...
World's largest table has been created.
LCDs are making them obsolete, but CRTs (which we all know and loved) work by accelerating electrons to a few keV. The electrons are moving at a not insignificant hunk of the speed of light and produce X-rays as they slam into the front of the tube.
Next time you're sitting in front of one, remember that there's an unlicensed particle accelerator a couple of feet from your brain.
Seriously, I had a malfunctioning CRT once.
My eyes and face felt like they were getting pin-pricked to death.
I gave it to charity "for parts."
I magic-markered a warning label on the screen and case first.
In 1947, four high school students in El Cerrito, California built a cyclotron. Here's a PDF of an article from Physics Today.
