Hardware Hacking 106

holy_calamity writes "CERN have released images of the damage done to the world's most powerful machine, the Large Hadron Collider, when an electrical fault caused a helium leak. New Scientist has posted them, along with explanations of what you can see. The sudden burst of gas shifted some of the huge superconducting magnets by half a meter, causing at least $21 million in damage."

The Large Hardon Collider [today.com] is designed to pump various types of hardon up to huge energies before banging them together. However, many concerned citizens without the personal experience or understanding of what hardons do worry at the idea of the large hardons being sucked deep into a black hole.

The device will push large, energised hardons through a ring repeatedly, faster and faster, as smoothly and tightly as possible, until they clash and spray matter in all directions. "It's nothing that cosmic rays don't do all the time all over the place," reassured a particularly buff scientist. "It's perfectly right and natural."

Low-energy hardon physics and the temperature dependence of hardon production are well understood, as is the process of a hardon smoothly entering the nucleus. But some question what may happen at greater, hotter energies.

Church leaders have come out at the device. "They're the same polarity!" said Pope Palpatine XVI. The Church worries that strange matter may recruit normal matter and turn it strange.

After a premature ejaculation of gas, the Large Hardon Collider has been delayed until July 2009. "I'm so sorry," stammered a scientist, "this has never happened to us before."

Too bad Congress killed the SSC in Texas... (5, Interesting)

Zymergy (803632) | more than 5 years ago | (#26094727)

Ah, through the "wisdom" of the US Congress, the SSC (Superconducting Super Collider) was killed over a mere $12 Billion cost savings (which was well under construction just south of Dallas, TX). http://en.wikipedia.org/wiki/Superconducting_Super_Collider [wikipedia.org]
Some say it was largely due to infighting with 'higher educational interests' back East and in the Chicago area, - but really the answer most likely due to nothing more than Greed and Money.

TO think that The US Federal Government will give taxpayer money to banks et al to the tune of $2 Trillion with NIL oversight and NIL public disclosure is extremely dangerous and shortsighted. ( http://www.bloomberg.com/apps/news?pid=20670001&refer=home&sid=aXNaCKxb.oIs [bloomberg.com] )

We (in the US) could have had something MORE POWERFUL than the LHC here in the US. (As I try not to think about the high-energy physicist brain-drain to France/Switzerland)...
Once upon a time, the US took pride in having the best and coolest toys the world over... (/sigh)

I could not agree more, but some can make the argument that the financial bailout was good for the economy. OK lets say it was and that in general people felt it was a good thing.

The military has spent how much per-month on the wars in Afghanistan and Iraq? Approaching $5 Billion per-month (http://www.usatoday.com/news/world/iraq/2003-09-07-cover-costs_x.htm) you only need 3 months of that to completely offset the costs of the SSC.

pz (113803) | more than 5 years ago | (#26095047)

The worst part about the SSC is mentioned in the parent comment's parenthetical comment about brain drain.

When the SSC was cancelled, there was a flood of high-energy physicists who were suddenly out of work. The US lost an entire generation of talent in physics. Instead of continuing on with a remarkable collection of centers of excellence, each themselves breeding excellence, and maintain the intellectual, scientific, technical, and economic advantages that the US Government prides itself on, the (pardon me) boneheads in Congress thought it better to continue the long slog toward mediocrity.

High-energy physics no longer happens in the US (my apologies to readers at LL, LANL, Brookhaven, Fermi, Argonne, Berkeley, and so forth). It happens in Europe and will continue to do so for the forseable future.

And by an odd coincidence, that['s about when particle physics took a detour into String Theory from which it has yet to recover. Almost nothing of value has happened in the field (especially in the US) since the SSC was canned. But hey, we can toss $30B to bail out the executive bonuses for a bank and not think twice about it (or even once).

And by another odd coincidence, other particle physicists took a detour into Wall Street, where they applied their advanced mathematical knowledge to creating exotic derivatives like Credit Default Swaps, but arguably without proper financial training or real-world experience. One is tempted to wonder whether the U.S. might be ahead by $2 trillion - $12 billion = $1.988 trillion had they just gone and financed the SSC instead.

SSC & SDI (1)

ErkDemon (1202789) | more than 5 years ago | (#26099849)

Back then, the US needed a bank of high-energy particle physicists for the Star Wars project. SSC was supposed to be the "white" counterpart of the SDI project, encouraging students into the field, and helping to develop the associated industrial infrastructure - SDI coudl then tap into that infrastructure and skills base.

Once it became apparent that the original SDI project(s) weren't going to happen, part of the strategic justification for priority-funding SSC disappeared.

cmdahler (1428601) | more than 5 years ago | (#26095807)

I dunno - if I had been in Congress back in 1993 I might have had some doubts about a project that had initially been sold to the government for about $4.5 billion and then ballooned to over three times that amount before the tunnels were even completely dug. There may have been a lot of factors involved in the cancelation of this project, but shutting off a pretty big spigot of wasteful public spending through inept mismanagement and fund milking certainly played a role in Congress' decision. I was living in Dallas at the time and had just graduated a few years before that in physics, so I kept pretty close to all the news stories. The DOE at the time couldn't manage its way out of a wet paper bag, and the wasteful spending and siphoning of funds made the whole thing look like the Big Dig in Boston. To be honest, it's really no wonder Congress canceled the project. At the rate they were going, it would have cost upwards of 20 billion to finish the project, and remember that we were also contributing a huge amount of money to the ISS at the time and had also just come out of a recession, so everyone was real leery about all that money. Wrong time, wrong management, that's ultimately what killed the SSC.

On the plus side, it gave Texas the world's finest all-weather underground go-karting track.

Actually, I'm really quite disappointed in the computer games community, that they haven't used a revamped SSC as a fictional location for a racing game. I mean, you have nice tubular tunnels which means that cars can loop-the-loop and do all sorts of cool things ... at maximum speed, the driving view would be at ~90 degrees to horizontal in the bends ... just needs some section colour coding, a bunch of floating camera pods and some bolt-on gadgetry (viewing stations, etc) for the cars to avoid. Maybe some rocket launchers.

While I won't go so far as to say that the problems with the LHC are cool, I do think it is to be expected. The LHC is a highly complex instrument with countless sub-assemblies and parts. I am sure that every effort was made to model the interaction of all these parts but the truth is that no one knows how it will perform untill it is physically assembled and then put into use. To expect it to work without incident as soon as it is powered up is unrealistic.

Compare it to the design and construction of a modern day airliner. Computer models are used to design, plan and aid in construction but a full size working aircraft is still produced before they start shipping them off to waiting customers.

"A resistive zone developed in one of the electrical connections, creating an electrical arc that punctured one of the helium enclosures around a magnet, according to an analysis by CERN.

Kinda curious as to what the ratio is for mass:volume for liquid helium and vaporized helium? ie if you have one liter of liquid helium if that were to turn to gas what is the volume then? You'd tend to think the'd have come up with that and figured out how much pressure would be in the lines so those relief valves could handle it.

Re:I liked the earlier description... (1)

Quietust (205670) | more than 5 years ago | (#26096519)

Wikipedia [wikipedia.org] lists an expansion ratio of 1 to 754 for liquid helium, which would certainly explain the amount of pressure exerted when it leaked.

Anyone who has been following these developments closely knows that the "helium leak" is just a cover story for the out of control mini black hole they created when they turned it on. Those magnets were shifted when they were finally able to collapse down the black hole, it went out with a massive gravitation burst (measured by seismographs as far away as the USGS Hawaii Volcano Observatory) that damaged a lot more equipment then they are letting on. Now that they know how dangerous it is, I wouldn't count on them ever turning on the Large Hardon Collider again.

Does the $21M cover the repairs to the damage done by the gas leak directly, or to that and the changes needed throughout (I would imagine) the entire system to make sure it doesn't happen again? I mean, since it failed the test and the electrical wiring couldn't handle the high current, won't they need to upgrade all the wiring? Either way, $21M really doesn't seem that bad for a project of this magnitude, I mean, what is that, the annual profits of an average smallish medium sized business?

Re:So (2, Informative)

Werthless5 (1116649) | more than 5 years ago | (#26095841)

We don't need to rewire the whole system, only a small batch of magnets that received the bad soldering job. The rest are fine, and we now have better ways of checking the soldering points remotely (ie without having to heat up the other 7 sectors of the LHC).

The $21M covers all repair costs, including replacing some of the wiring in a batch of magnets in a particular sector. Actually, part of the plan is to use backup magnets (obviously double checked for this flaw) so as to save some time, but we don't have enough backup magnets to replace all of the ones that need to be fixed.

Re:So (1)

ErkDemon (1202789) | more than 5 years ago | (#26099897)

Are we sure that it's only a small batch of magnets that "received the bad soldering job"? I thought that the reason why the joint failed was still supposed to be an educated guess (since the joint in question completely vaporised, leaving us with nothing to examine).

But maybe there's been some new information since last time I checked. Any pointers?

Re:So (1)

ErkDemon (1202789) | more than 5 years ago | (#26099871)

AFAII, there are still two repair options on the table.

The "quick" option is estimated to give them (reduced) beam in late summer 2009.

The "serious" option involves fitting a new exhaust system to every section of the ring, and means that they'll miss 2009, and we'll be looking at 2010.

MRI Quenching (1)

jellomizer (103300) | more than 5 years ago | (#26095375)

MRIs have a feature called quenching. Where when there is a problem there are small heaters which heat the Liquid Helium to a warmer temperature (that closer to liquid Nitrogen). So you don't break your million dollar MRI. But loose a Thousand dollar supply of Liquid He

Re:MRI Quenching (4, Informative)

blueg3 (192743) | more than 5 years ago | (#26096005)

That's not a feature, that's a side effect. Some types of failure cause the liquid helium to warm up until the magnet is no longer at superconducting temperatures. This causes a sudden resistance, which can damage the magnet, heats the whole system up (boiling off the coolant), et cetera. MRI systems generally have an emergency shutoff feature, the side effect of which is magnet quenching.

In this case, a quench is what happened -- resistance in the circuit caused helium boiloff, which destroyed superconductivity. They have many safeguards for this, as this was well-known before the first MRI or superconducting collider was built. Release valves allow the boiling helium to escape, and resistor banks are used to draw off electrical energy from the system. However, their system wasn't sufficient to handle the level of failure that occured.

No. The magnet quenching is often the emergency shutoff feature. The point is that you want the whole superconducting circuit to lose the superconducting state at once, instead of a local hotspot which would melt a part of million dollar coil. Sometimes only heat conductors are used to distribute the sudden energy released, sometimes you redirect the current to a resistor that heats up the whole system - I think the latter was what GP was talking about.

Clearly this was an act of Divine Intervention...

Re:There is a GOD (3, Funny)

Right now all of the detectors are calibrating with cosmic rays.

I'll consider it an act of Divine Intervention when God uses cosmic rays to spell "TURN THIS SHIT OFF" on every detector.

Until then, let's fix this black hole device!

From the energy out of thin air department (1)

bokkepoot (143872) | more than 5 years ago | (#26095467)

What makes CERN so unique, is that per the article "Large amounts of helium vaporised, causing several magnets to heat up"

Re:From the energy out of thin air department (1)

Werthless5 (1116649) | more than 5 years ago | (#26095947)

That's exactly how it happened. There was essentially a spark that went through a helium container, causing the helium to vaporize (from its liquid state).

Liquid helium is what is being used to keep the magnets cooled. When the helium vaporized, it heated up. Thus, the helium vaporization caused several magnets to heat up.

There is no way for a superconducting magnet to heat up on its own because it's a superconductor; no power is ever lost to heat as there is no resistance in the wiring!

Re:From the energy out of thin air department (1)

blueg3 (192743) | more than 5 years ago | (#26096085)

That's exactly what happened.

Can't help it if you don't understand superconducting electromagnet failure modes.

Large Hadron Goatse cookies (1)

David Gerard (12369) | more than 5 years ago | (#26095525)

In honour of the LHC starting up in September, my girlfriend made some celebratory cookies [today.com] ... of the Large Hadron Goatse. Note the gold ring.

Ah, but don't go home with your hadron [sonymusic.com]
It will only drive you insane
You can't shake it (or break it) with your Motown
You can't melt it down in the rain.

i wonder who squealed... (1, Interesting)

Anonymous Coward | more than 5 years ago | (#26095881)

New Scientist broke these pix, not CERN. I'm pretty sure i know who took those pix (not gonna tell!). "We" where i work have had them for a while, and have elected NOT to spread them around and allow CERN to put them up themselves. I guess someone decided to "help" them out. It is debatable as to the moral rectitude of this decision, but I could have put these up weeks ago and chose _not_ to.

As i understand it, the pictures you see are taken 5 half-cells away from the primary failure, or somewhere around 50+ meters from the explosion.
Wow, huh?

Note the red things in the picture, those are magnet stands, ripped out of the concrete. The magnet body in that shot is sitting on wood cribbing -- it was sitting on the floor. You can deduce the displacement form careful examination.

Berry ++ ungood. We all feel badly for them and wish them the best of luck.

Adjacent Universe Anomaly (1)

gluefish (899099) | more than 5 years ago | (#26096055)

One of my sources ( the one I use the tinfoil hat to talk to ) reports that in one of our adjacent alternative universes there is a black hole where Earth used to be. The last message through that pipeline was from one of the Cern engineers, saying "Watch This!" They have had to seal the connection to that universe to prevent our universe from being sucked through the pipe by the black hole at the other end.
