LHC Fully Documented Online
Physicser writes "Want to read every single technical detail of the design and construction of the Large Hadron Collider and its six detectors? The whole shebang — seven reports totaling 1600 pages, 115 MB, with contributions from 8000 scientists and engineers — has been published electronically by the Journal of Instrumentation, free to read without a subscription."
Not particularly.
This is something to download, store away, and reminisce some 30 years later.
It would be a great read if I was one of the ten people on the face of the planet who could actually understand every detail. Oh, sorry, that's the people who wrote it.
I know it's going to get downloaded a ton of times and probably deleted before most readers ever get to the 3rd page, if it's even read at all.
Save them poor guys some bandwidth, torrent it. Too many people are going to be wasting their resources with no serious intentions of reading the contents.

If you need me, I'll be in my basement.
A work that expires before its copyright never enters the public domain and thus enjoys eternal copyright protection.
Now I can build my own the planet is DOOMED!
...1600 pages for every detail of the making of a LHC, 6546 pages in the specs for OOXML and it's still not enough detail to let you open and create OOXML documents. Obviously the LHC is not adequately complex.
TL;DR
This rather witty, clever. And not extremely obvious signature is precisely one hundred and twenty characters in length.
Don't you mean your parent's basement?
No sig for you!!
I recall hitting numerous sections of the site that were protected. One was a log of superconducting magnet quenches. I guess that openness doesn't extend to embarrassing operational problems...
Please help metamoderate.
I am very much looking forward to what comes out of the LHC. It's been wonderful to watch its construction and that's only a fraction of the satisfaction its discoveries will provide.
Play me online? Well you know that I'll beat you. If I ever meet you I'll "/sbin/shutdown -h now" you. -Weird Al, kinda.
At sixteen hundred pages, it can only create about a fourth of the suckiness of the OOXML standard. Since that hasn't generated a black hole - except for maybe a few terabytes of lost data here and there - we should be safe.
Dewey, what part of this looks like authorities should be involved?
I have actually done some theoretical calculations based upon other people/scientist's "crazy" theories, and it is possible that an explosion the equivalent to a 3 gigaton TNT explosion ( http://en.wikipedia.org/wiki/TNT_equivalent ) to be created. Depending on where is happens, it might create a crater or hump ( http://nuclearweaponarchive.org/Library/Effects/UndergroundEffects.html ), but probably a crater between 10 kilometers to 18 kilometers wide. This explosion would probably create an earthquake between 8.5 and 10.5 on the ritcher scale ( http://en.wikipedia.org/wiki/Richter_magnitude_scale ) that is felt in Geneve, Switzerland, and an earth quake between 7 and 8.5 felt in Paris, France. The fun thing is that the amplitude of the quake would be very large, and the ground might not even shake more than twice due to the size of the whole thing.
Please note that these calculations assume that all the equipment works perfectly (, or a error of less than a thousandth of a percent). I did account for error in the calculations, especially how practical large/nuclear explosions tend to have caused slightly larger earthquakes than calculated ( http://oai.dtic.mil/oai/oai?verb=getRecord&metadataPrefix=html&identifier=AD0617181 ).
Other notes: There exists a chance that a huge explosion would just create a big crater with a small tunnel going toward the center of the earth. If you have trouble visualizing this, try visualizing the Death Star.
Is anyone else putting their aluminum foil hats on and thinking that these scientists are absolutely mad?! And why did these mad scientists get to have a chance to destroy the world before me?
It's a hobby, I'm way outside of the brainpower to do the math.
So I found some videos and articles to help me out: YouTube to the rescue Warning there's some crap with bird in there.
Finding the Higg's Boson is the big prize, if they find it it will help with this which disrupts the notion of black holes as "singularities" and raises some philosophical, and religious questions... largely if the theorized particle is not found.
Also interesting is the evaporating black hole theory, which is all but proven so don't worry (Cough CNN).
Personally I've always been facinated by Virtual particles and am curious about the implication of examining non-singularity black holes.
Enjoy it, it's gonna be cool as hell!
The LEGO Mindstorm version will be released any day now!
It's a small world and it smells funny; I'd buy another if it wasn't for the money; Take back what I paid (SoM)
On page 867, there's mention of a two-meter-wide thermal exhaust port, right below the main port. The exhaust shaft leads directly to the reactor system, and a precise hit would start a chain reaction which should destroy the LHC.
Village idiot in some extremely smart villages.
I thought that there will be no 30 years later after they turn on the machine...
I especially like appendix B, or "Build Your Own Large Hadron Collider"
I totally have a project for this weekend!
Home Depot has extra large superconducting electromagnets, right?
...now we have to worry about random third-world countries building weapons of mass-collision.
Come on, don't you remember the slashdot article about it?
Twenty-seven kilometers of tunnel under ground
Designed with mind to send protons around
A circle that crosses through Switzerland and France
Sixty nations contribute to scientific advance
Two beams of protons swing round, through the ring they ride
Til in the hearts of the detectors, theyre made to collide
And all that energy packed in such a tiny bit of room
Becomes mass, particles created from the vacuum
And then
LHCb sees where the antimatters gone
ALICE looks at collisions of lead ions
CMS and ATLAS are two of a kind
Theyre looking for whatever new particles they can find.
The LHC accelerates the protons and the lead
And the things that it discovers will rock you in the head.
Come on, let's drop some particle physics in the club!
Rock Us, Dukakis.
Being able to duplicate an experiment is important to science, so we obviously need many people to build Large Hadron Colliders. I'm not doing anything this weekend, so where's the party?
I was expected at least a mirror and placeholder wiki at openlhc.org by now.
If anyone ever needs a reason to wallop copyright, let this quote from the article be that reason;
Most copies of The Blue Book had vanished from the SLAC Library, and the librarians wanted to make it available electronically. But they ran into a snag: No one could figure out who owned the copyright, so there was no one to give permission to put it on the Web.
"It's an orphan work," SLAC archivist Jean Deken told me Friday. The original publisher was bought by another, which was bought by another, and so on. Finally, with the help of an expert from Stanford Law School, librarian Abraham Wheeler tracked down the current owner of the copyright-which said that since it could not find any documentation on the book, it could not grant permission to reproduce it.
I reserve the write to mangle english.
Are they mad? The work of thousands of scientists published on line for all to see. A reasonable generic copyright license. All downloadable.
What about the poor deserving lawyers? Where is the DRM? The commercial propaganda about "IP"? The hundred page license? The attempts by assorted hangers on to profit at other people's expense?
I think the lawyers should form a class action lawsuit for loss of income. It's just not right that somebody should be able to do something without numerous lawyers attached.
I think we need stronger laws to prevent the pirating of particle colliders.
My house is rather small. Perhaps I could build a Medium, or even a Small Hadron Collider?
Ezekiel 23:20
I am not in TOTEM (other side of the ring) but I understand the abstract just fine and consider it an immensely valuable contribution to the physics programme of the LHC.
These weren't written to be read end to end by the layman. They were meant as reference publications for professionals. I don't know how I would have gotten through my ph.d. without publications like these. Where else do I get the exact layout of the ATLAS semi-conductor tracker? Where else do I look for the muon momentum resolution of CMS vs. ATLAS? I am sorry if you think that renders them incomprehensible but this is what we need.
Help to save the world from being destroyed by a black hole! The specs to the LHC (Large Hole Creator) are available. Create a detailed proof showing that the LHC will create a planet-destroying black hole when it is switched on. Send the proof, with your $75 entry fee, directly to me. The person submitting the first valid proof will be awarded a prize of $50 Million, to be awarded on Sept 12th.
Isn't it funny that the entire LHC spec is 1.600 pages, while the OOXML documentation, as submitted by Microsoft, is a full 6.000 pages.
Does this reflect a difference in complexity, or is it a sign of something else?
Well, first of all, some of us have better taste than to wear a loincloth. A robe and wizard hat, for example, is much more stylish and comfortable for the aspiring sorcerer or warlock. A toga picta works too, for the aspiring Emperor. Well, at least until mom catches wind that you dyed one of her bedsheets purple ;)
But a loincloth? Ugh. We're civilized people, not some barbarians.
Second, some of us have our own basement to defend, thank you very much. I mean, have you tried taking over the world from your mom's basement? Ooer, talk about frustrating. It would go sorta like this.
Me: "Now we open the prayer books to the dark invocation psalm and..."
Mom (poking her head in): "Anyone want milk and cookies?"
Cultist 1: "I'll have some, please."
Cultist 2: "Me too."
Me: "Mooom!!"
Mom: "Oh, hush. Nice dress, by the way."
Me: "Mom, it's a robe."
Mom: "Sure it is. I just want you to know me and dad support your lifestyle choices."
Cultist 3: "Told you it looks gay."
Cultist 1: "Yeah."
Me: "Mom, you're interrupting our invocation!"
Mom: "Oh, hush, I'm your mom, I'm allowed to. What are you guys playing anyway? Dungeons and Dragons?"
Me: "No, it's serious. And you can start calling me High Overlord Moraelin the First."
Mom: "High, huh? Well, you know me and dad don't approve of _that_, but I guess it would explain a few things."
Cultist 4: "Heh!"
Me: "*sigh* Where are the sacrificial dagger and the sacred chalice anyway?"
Mom: "You mean our kitchen knife? I put it in the dishwasher, together with that plastic cup you had there. They were getting ridiculously dirty, and it's just not healthy."
Cultist 3: "Told ya."
A trip to the kitchen later:
Group chanting: "Nigrae legiones, ferus imperator, sinus occultus, fatum terminatum"
Mom (poking nose in again): "By the way, I'm going to sleep. Try to keep the noise down, please."
Me: "Ok, mom."
Mom: "By the way is that the chorus from Das Omen?"
Me: "No, it's an ancient and sacred invocation.."
Cultist 2: "Nah, I googled it, it's E Nomine."
Cultist 1: "Owned."
Cultist 4: "I thought you said you only listened to metal?"
Me: "Gah! Fine by me, chant Dies Irae if it makes you feel any better."
Cultist 3: "Why do we have to chant in Latin anyway?"
Me: "Because we're summoning an arsehole of a demon, and he wants it that way."
Mom: "Anyway, keep it down and turn off the lights when you're done, ok?"
Me: "Ok, mom. Now where were we?"
Cultist 3: "You know, screw this. Let's skip the henchman and work for the real overlord. Do you happen to need some accolytes, Mrs?"
Cultist 1: "Seconded."
Cultist 2: "No kidding."
Cultist 4: "Actually, I'm out of here. I promised mom I'll be home by eleven anyway."
