CERN's Pioneering Mini-Accelerator Passes First Test (nature.com)
An anonymous reader quotes a report from Nature: An experiment at CERN has demonstrated a new way of accelerating electrons to high energies -- one that could dramatically shrink the size of future particle accelerators and lower their costs. The technique is the latest entrant in a hot race to develop a technology called plasma wakefield acceleration. The method uses waves in plasma, a soup of ionized atoms, to push electrons to ever-higher energies over distances much shorter than those required in today's particle accelerators. Several laboratories have demonstrated plasma wakefield acceleration using two different approaches; most teams use laser beams to create the plasma waves needed. The latest work is the first to show that protons can also induce the waves and achieve electron acceleration -- a technique that may have advantages over the others because protons can carry high energies over long distances.
In this case, researchers diverted protons that would usually be fed into the Large Hadron Collider (LHC) at CERN, Europe's particle-physics lab near Geneva, Switzerland, and instead inserted them into the wakefield accelerator, called the Advanced Wakefield Experiment (AWAKE). The machine worked as expected and created a consistent beam of accelerated electrons. "That, for us, was a major achievement," says Matthew Wing, a physicist at University College London, who is deputy spokesperson for AWAKE. "It essentially says that the method works, and it's never been done before." The work is described in Nature on 29 August.

Stein's Gate Confirmed
eh? most science and tech budgets fell under Obama though he promised doubling them. Hilary would do differently?

You have made a souped up ION implanter.
Actually this does have some cool possible uses in faster plasma drives.
I post as AC because I really don't give a crap!
I suspect Obama had very little control over budgets while he was in office. Congress has the power of the purse. He had some influence over congress for the first two years. The other 6 was pretty much congress doing the opposite of whatever came out of his mouth.
Can't we just tell the guy protons that their girl is bonding with another nucleus, and let nature sort it out?
Or. As the kids are saying, Awoke.
I won't even pretend to be intelligent enough to discern the ramifications of this development, yet it seems plausible this is a big advancement.
QWouldn't it be great if our ability to advance technology outpaced our tribalism-based predisposition towards self-destruction?
Happiness in intelligent people is the rarest thing I know.

Mod to +10000000.
It's why the guy had to do so many executive orders. But go ahead and keep criticizing the man.
That was a rather complicated read... Increased particle acceleration firing electrons into a mix of more electrons and positive ions instead being in a vacuum.
To what end, I have no idea. But interesting.
Regarding the movie, from one paragraph in TFA:
1. Super Proton Synchrotron
2. rubidium plasma
3. A specially built smaller accelerator produces electrons that are inserted in the protonsâ(TM) wake.
4. Energies in even the 50-GeV range could be useful for experiments in which electrons are shot at a fixed target.
#3 and 4 have me mystified, great lines for a mad scientist.
Plot: Just have reality rip apart rather than some earthquake, tsunami, meteor, or Sharknado. Reality rips like broken glass, spreading from the experiment center. There is a twist ending.
Someone write the script, let's get this movie made!

Your right when you say Obama had very little control over the budget but that also applies to all of his predecessors and the current President. And it's about time all those who are endlessly badgering and protesting the executive branch realize the President has very little real authority to change anything of importance. A President doesn't wield the power of an Emporer. Even as Commander in Chief the President can declare war and deploy the military but Congress can override that decision after 90 days by defunding the military. A President has veto power but even that decision can be overridden by Congress. And Presidents will only invoke a veto if they are 100% sure that veto would not be overridden by Congress. Having a veto overridden makes a President look weak. Don't like US immigration policies? Blame Congress who are the ones who passed the current laws. All Trump has did is enforce the laws and regulations voted into law by Congress. President can issue Executive Orders but they can also be overridden by Congress or the court system. Obama used an Executive Order to protect the DACA immigration program. At the time this decision came very close to violating the separation of powers. Trump did not cancel the DACA program he turned the program over to Congress so they could replace the executive order with a legal constituted law. He gave Congress more than a year for Congress to act and they did nothing. Presidents can't fuck up a country only Congress is capable of that and they have been doing a bank up job. They have no term limits. They have no limits on financial contributions to their campaigns. They cannot be forced to testify in public when accused of wrong doing. They love to summon people to Congress for public enquiries but they are protected from being grilled in public over their statements and actions. Over the years they have consolidated power in the various committees and sub-committees to ensure no new Congressman have any real power to effect any thing important. They always attach some non-related issues onto any important peace of legislation and are perfectly willing to harming the country to gather as much pork as possible for all the people who invested millions of dollars getting them elected. And this type behavior comes from both the Democrats and Republicans in equal measure. And they are experts at focusing the raging mobs attention on the executive branch to ensure nobody realizes that they are the true source of the political dysfunction and it doesn't matter who the President is.
Mini-Accelerator Passes First Test
Which Mini? Hardtop 2 Door, Hardtop 4 Door, Countryman, Clubman, Convertible, ... - what?
It must have been something you assimilated. . . .
You're a moron, learn your from you're. The rest is sure to be drivel (you might say dribble) if you can't figure out you're.
Good news. Just in time to get one cancelled in Texas.
Have gnu, will travel.
Define "advanced".
It's harder than you might think, to pick something that is not completely arbitrary. If possible at all.
You're a punk. Learn to use semicolons.
"Maybe now you'll never slime a guy with a positron collider huh!"
If you've ever wanted a particle accelerator on your desk, and a CRT monitor just doesn't do it for you, I found just the thing.
Plasma. And the fact that people have been working on them for decades with nothing to show for it.
This was a big story in Canada circa 1989 because they built a surfatron and reached some new limit. Now it's 30 years later and we're still not using them. Maybe in another 30 years?
It's not an accelerator, it's a matter destructor.

Yup. Deficits (and the debt) was bad until Trump and GOP had control and then they were okay if they were tax cuts.
The US is heading towards annual $1T deficits.
So much for deficit hawks.
