Dr. Egon Spengler: I blame myself.
Dr. Peter Venkman: So do I.
Dr. Raymond Stantz: Well, no sense in worrying about it now.
Dr. Peter Venkman: Why worry? Each one of us is carrying an unlicensed nuclear accelerator on his back.
Didn't the Large Electron-Positron Collider fail to detect evidence of the Higgs Boson?
It didn't produce a negative result. In fact, they were seeing some small hints of something around 114 GeV right as they shut down for the LHC construction.
The hints at 114GeV in LEP were very subtle and have since been shown to be a statistical fluctuation (which is unsurprising). The Large Hadron Collider (LHC) has observed the Higgs boson at 125GeV. This mass is too high for LEP to have ever seen without further upgrades to boost it's energy and there was no reason to expect it to be as close as it is to the LEP energy. It could easily have been 200GeV+ and well outside of LEP's capabilities.
The advantage of the LHC is that is was capable of much higher energies due to being a proton collider (currently 13000GeV), though this comes at the cost of being "messier" to analyse the data. Additionally, continuing to run LEP to check would have further delayed the LHC which would have been very expensive.
"On 4 July 2012, the ATLAS and CMS experiments at CERN's Large Hadron Collider announced they had each observed a new particle in the mass region around 126 GeV. This particle is consistent with the Higgs boson predicted by the Standard Model."
"LEP – the largest electron-positron accelerator ever built – was dismantled in 2000. Its 27-kilometre tunnel now hosts the LHC"
If so, staging is an issue from what I understand. Even at 100GeV/m, you'll need many stages to reach interesting TeV territory, so this is a crucial aspect if it wants to beat the LHC.
Some relevant discussion on PhysicsForums: https://www.physicsforums.com/threads/two-stage-electron-wak...
As I understand it, you can't just build a pipe and get the full gradient for X meters. Rather you build a (relatively) small device which has the 100GeV/m gradient, and then you'd glue many such devices back-to-back. So you get some overhead from the interconnects etc. Still, with 10x overhead it's "only" one mile.
The other point is that not all applications need TeV scale. For such applications maybe just a few stages would be sufficient. In which case it might be room-size or less.

I can't seem to find an archive either.
PDF is surprisingly freely available.
Incidentally, the full text of the article is available in HTML too, which might be easier on mobile.
The figures in the article, with lasers reflected by mirrors and particle beams going through the mirrors, suggest a very small but decently powerful single stage accelerator; using this technique as a building block for a large accelerrator isn't discussed.
All while the country is teetering on edge and could drag down its neighbours into another recession (selfmade this time), the NHS and local authorities remain in crisis, pound is weakening and inflation keeps going up.
It sucks being stuck sort of speak between 2 of your good neighbours undergoing a mental breakdown and self harming

If you really want to rant about the media spinning brexit lies then go ahead - you'll find plenty of willing listeners, but at least try and do it on a news story that actually fits your argument?
Firstly, inflation is not going up, at least I couldn't find any evidence of that.
Secondly, looking at the UK trade partners (for instance here http://www.worldstopexports.com/united-kingdoms-top-import-p...) I see that UK has trade deficit will all EU countries, given the fact that UK has well develop economy they can in fact gain on leaving UK and relaying on bilateral deals (and I guess those who are bashing UK most will be first in the queue to start trading with them - Germany approach to Nord Stream that can be potentially dangerous for EU energy safety shows that when it comes to money, EU "unity" is thrown away quickly).
Third, weakening pound is actually good for UK, the goods they produce are cheaper, so event if imported goods are more expensive at some point this will come to equilibrium.
Fourth, UK has still hidden gems like tax havens here and there, including the one at the very center of London - quite convenient for all the rich people who, accidentally, have also a lot of political power and surely they would not like UK to be hurt too much.
The only danger I see is that Scotland might try to gain independence and walk away with the oil taken from the North See, this would shrink UK domestic market and could indeed do some harm.
This is an absurd fantasy. If trade deficits on their own made you poorer, the UK and US would have been reduced to third world status decades ago. The Uk has very low unemployment, there just isn't a free labour pool available to move into manufacturing. Hands up anyone from the UK here who wants to give up their job to go on to a production line, or wants that for their children? Forcing people out of better paid more valuable jobs into low end manufacturing, driving up costs for UK consumers, to serve some mercantilist daydream won't make the UK any richer.
Does the government care about manufacturing? They closed the mines and moved towards a "service economy" last I heard..
> who wants to give up their job to go on to a production line, or wants that for their children? Forcing people out of better paid more valuable jobs into
There are northern towns that would love those jobs. Their children are currently at lidl checkout counters and behind pub bars.
Hey , Ireland here, you're completely ignoring cutting our island in two again which will very likely lead to a resurgence of the IRA.
>Third, weakening pound is actually good for UK, the goods they produce are cheaper, so event if imported goods are more expensive at some point this will come to equilibrium.
Yeah and the young generation brexitors have screwed over will be old by then.
Secondly, the UK is primarily a service economy, and Brexit will devastate large swathes of the service industries.
Third, this is a standard talking point, and is unsupported by facts - one reason (there are others) being that increased import costs for physical goods from tariffs and a declining currency balance out any possible gain from extra income.
Fourth - I don't think trying to turn tax avoidance into the UK's primary economic activity is a terribly good idea. You may disagree, of course.
Scotland will indeed walk away. Ireland will... change. Gibraltar will turn into even more of a mess than it is now.
And so on.
There is in reality absolutely no upside to Brexit. Except for traders shorting the pound, there are no non-imaginary opportunities - only massive costs and disruptions.
And propaganda and PR won't change that. There's certainly been an uptick in British flag waving in the UK, but it takes more than that to run a modern economy.
The irony being that Brexit will destroy the industries the UK is a world-class player in - financial services, law, tech research, engineering, science research, and the arts.
Sorry your comment just really made me think about the book 1984.
